                            CONVEYANCE OF TRUST FUND
                         REPRESENTATIONS AND WARRANTIES

         Section 2.01      CONVEYANCE OF TRUST FUND.

                  The Seller hereby sells, transfers, assigns, sets over and
otherwise conveys to the Depositor, without recourse, all the right, title and
interest of the Seller in and to the assets in the Trust Fund.

                  The Seller has entered into this Agreement in consideration
for the purchase of the Mortgage Loans by the Depositor and has agreed to take
the actions specified herein.

                  The Depositor, concurrently with the execution and delivery
hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to the
Trustee for the use and benefit of the Certificateholders, without recourse, all
the right, title and interest of the Depositor in and to the Trust Fund.

                  In connection with such sale, the Depositor has delivered to,
and deposited with, the Trustee or the Custodian, as its agent, the following
documents or instruments with respect to each Mortgage Loan so assigned: (i) the
original Mortgage Note, including any riders thereto, endorsed without recourse
to the order of "JPMorgan Chase Bank, as Trustee for certificateholders of Bear
Stearns Asset Backed Securities, Inc. Asset Backed Certificates, Series
2003-AC4," and showing to the extent available to the Seller an unbroken chain
of endorsements from the original payee thereof to the Person endorsing it to
the Trustee, (ii) the original Mortgage and, if the related Mortgage Loan is a
MOM Loan, noting the presence of the MIN and language indicating that such
Mortgage Loan is a MOM Loan, which shall have been recorded (or if the original
is not available, a copy), with evidence of such recording indicated thereon (or
if clause (x) in the proviso below applies, shall be in recordable form), (iii)
unless the Mortgage Loan is a MOM Loan, the assignment (either an original or a
copy, which may be in the form of a blanket assignment if permitted in the
jurisdiction in which the Mortgaged Property is located) to the Trustee of the
Mortgage with respect to each Mortgage Loan in the name of "JPMorgan Chase Bank,
as Trustee for certificateholders of Bear Stearns Asset Backed Securities, Inc.
Asset Backed Certificates, Series 2003-AC4," which shall have been recorded (or
if clause (x) in the proviso below applies, shall be in recordable form) (iv) an
original or a copy of all intervening assignments of the Mortgage, if any, to
the extent available to the Seller, with evidence of recording thereon, (v) the
original policy of title insurance or mortgagee's certificate of title insurance
or commitment or binder for title insurance, if available, or a copy thereof,
or, in the event that such original title insurance policy is unavailable, a
photocopy thereof, or in lieu thereof, a current lien search on the related
Mortgaged Property and (vi) originals or copies of all available assumption,
modification or substitution agreements, if any; provided, however, that in lieu
of the foregoing, the Seller may deliver the following documents, under the
circumstances set forth below: (x) if any Mortgage, assignment thereof to the
Trustee or intervening assignments thereof have been delivered or are being
delivered to recording offices for recording and have not been returned in time
to permit their delivery as specified above, the Depositor may deliver


                                      -41-

<PAGE>



a true copy thereof with a certification by the Seller or the title company
issuing the commitment for title insurance, 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"; and (y) in lieu of the
Mortgage Notes relating to the Mortgage Loans identified in the list set forth
in Exhibit J, the Depositor may deliver a lost note affidavit and indemnity and
a copy of the original note, if available; 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 Depositor, in lieu of delivering the
above documents, may deliver to the Trustee and its Custodian a certification of
a Servicing Officer to such effect and in such case shall deposit all amounts
paid in respect of such Mortgage Loans, in the Master Servicer Collection
Account or in the Distribution Account on the Closing Date. In the case of the
documents referred to in clause (x) above, the Depositor shall deliver such
documents to the Trustee or its Custodian promptly after they are received. The
Seller shall cause, at its expense, the Mortgage and intervening assignments, if
any, and to the extent required in accordance with the foregoing, the assignment
of the Mortgage to the Trustee to be submitted for recording promptly after the
Closing Date; provided that the Seller need not cause to be recorded any
assignment (a) in any jurisdiction under the laws of which, as evidenced by an
Opinion of Counsel addressed to the Trustee delivered by the Seller to the
Trustee and the Rating Agencies, the recordation of such assignment is not
necessary to protect the Trustee's interest in the related Mortgage Loan or (b)
if MERS is identified on the Mortgage or on a properly recorded assignment of
the Mortgage as mortgagee of record solely as nominee for Seller and its
successors and assigns. In the event that the Seller, the Depositor or the
Master Servicer gives written notice to the Trustee that a court has
recharacterized the sale of the Mortgage Loans as a financing, the Seller shall
submit or cause to be submitted for recording as specified above or, should the
Seller fail to perform such obligations, the Master Servicer shall cause each
such previously unrecorded assignment to be submitted for recording as specified
above at the expense of the Trust. In the event a Mortgage File is released to
the Company or the Servicer as a result of such Person having completed a
Request for Release, the Custodian shall, if not so completed, complete the
assignment of the related Mortgage in the manner specified in clause (iii)
above.

                  In connection with the assignment of any Mortgage Loan
registered on the MERS(R) System, the Seller further agrees that it will cause,
at the Seller's own expense, within 30 days after the Closing Date, the MERS(R)
System to indicate that such Mortgage Loans have been assigned by the Seller to
the Depositor and by the Depositor to the Trustee in accordance with this
Agreement for the benefit of the Certificateholders by including (or deleting,
in the case of Mortgage Loans which are repurchased in accordance with this
Agreement) in such computer files (a) the code in the field which identifies the
specific Trustee and (b) the code in the field "Pool Field" which identifies the
series of the Certificates issued in connection with such Mortgage Loans. The
Seller further agrees that it will not, and will not permit the Company, the
Servicer or the Master Servicer to, and the Master Servicer agrees that it will
not, alter the codes referenced in this paragraph with respect to any Mortgage
Loan during the term of this Agreement unless and until such Mortgage Loan is
repurchased in accordance with the terms of this Agreement or the Mortgage Loan
Purchase Agreement.

<PAGE>



                  (a) Based on the Initial Certification received by it from the
Custodian, the Trustee acknowledges receipt of, subject to the further review
and exceptions reported by the Custodian pursuant to the procedures described
below, the documents (or certified copies thereof) delivered to the Trustee or
the Custodian on its behalf pursuant to Section 2.01 and declares that it holds
and will continue to hold directly or through a custodian those documents and
any amendments, replacements or supplements thereto and all other assets of the
Trust Fund delivered to it in trust for the use and benefit of all present and
future Holders of the Certificates. On the Closing Date, the Trustee or the
Custodian on its behalf will deliver an Initial Certification in the form
annexed hereto as Exhibit C-1 confirming whether or not it has received the
Mortgage File for each Mortgage Loan, but without review of such Mortgage File,
except to the extent necessary to confirm whether such Mortgage File contains
the original Mortgage Note or a lost note affidavit and indemnity in lieu
thereof. No later than 90 days after the Closing Date, the Trustee or the
Custodian on its behalf shall, for the benefit of the Certificateholders, review
each Mortgage File delivered to it and execute and deliver to the Seller and, if
reviewed by the Custodian, the Trustee, an Interim Certification substantially
in the form annexed hereto as Exhibit C-2. In conducting such review, the
Trustee or the Custodian on its behalf will ascertain whether all required
documents have been executed and received and whether those documents relate,
determined on the basis of the Mortgagor name, original principal balance and
loan number, to the Mortgage Loans identified in Exhibit B to this Agreement, as
supplemented (provided, however, that with respect to those documents described
in subclauses (iv) and (vi) of Section 2.01, such obligations shall extend only
to documents actually delivered pursuant to such subclauses). In performing any
such review, the Trustee and the Custodian 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
on its behalf 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 on its behalf shall include such information in the exception
report attached to Exhibit C-2. The Seller shall correct or cure any such defect
or, if prior to the end of the second anniversary of the Closing Date, the
Seller may substitute for the related Mortgage Loan a Replacement Mortgage Loan,
which substitution shall be accomplished in the manner and subject to the
conditions set forth in Section 2.03 or shall deliver to the Trustee an Opinion
of Counsel addressed to the Trustee to the effect that such defect does not
materially or adversely affect the interests of the Certificateholders in such
Mortgage Loan within 60 days from the date of notice from the Trustee of the
defect and if the Seller fails to correct or cure the defect or deliver such
opinion within such period, the Seller will, subject to Section 2.03, within 90
days from the notification of the Trustee purchase such Mortgage Loan at the
Purchase Price; provided, however, that if such defect relates solely to the
inability of the Seller to deliver the Mortgage, assignment thereof to the
Trustee, or intervening assignments thereof with evidence of recording thereon
because such documents have been submitted for recording and have not been
returned by the applicable jurisdiction, the Seller shall not be required to
purchase such Mortgage Loan if the Seller delivers such documents promptly upon
receipt, but in no event later than 360 days after the Closing Date.

                  (b) No later than 180 days after the Closing Date, the Trustee
or the Custodian on its behalf will review, for the benefit of the
Certificateholders, the Mortgage Files and will execute and deliver or cause to
be executed and delivered to the Seller and, if reviewed by the Custodian, the
Trustee, a Final Certification substantially in the form annexed hereto as
Exhibit C-3.


                                      -43-

<PAGE>



In conducting such review, the Trustee or the Custodian on its behalf will
ascertain whether each document required to be recorded has been returned from
the recording office with evidence of recording thereon and the Trustee or the
Custodian on its behalf has received either an original or a copy thereof, as
required in Section 2.01 (provided, however, that with respect to those
documents described in subclauses (iv) and (vi) of Section 2.01, such
obligations shall extend only to documents actually delivered pursuant to such
subclauses). If the Trustee or the Custodian on its behalf finds any document
with respect to a Mortgage Loan 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 on its behalf shall note
such defect in the exception report attached to the Final Certification and
shall promptly notify the Seller. The Seller shall correct or cure any such
defect or, if prior to the end of the second anniversary of the Closing Date,
the Seller may substitute for the related Mortgage Loan a Replacement Mortgage
Loan, which substitution shall be accomplished in the manner and subject to the
conditions set forth in Section 2.03 or shall deliver to the Trustee an Opinion
of Counsel addressed to the Trustee to the effect that such defect does not
materially or adversely affect the interests of Certificateholders in such
Mortgage Loan within 60 days from the date of notice from the Trustee of the
defect and if the Seller is unable within such period to correct or cure such
defect, or to substitute the related Mortgage Loan with a Replacement Mortgage
Loan or to deliver such opinion, the Seller shall, subject to Section 2.03,
within 90 days from the notification of the Trustee, purchase such Mortgage Loan
at the Purchase Price; provided, however, that if such defect relates solely to
the inability of the Seller to deliver the Mortgage, assignment thereof to the
Trustee or intervening assignments thereof with evidence of recording thereon,
because such documents have not been returned by the applicable jurisdiction,
the Seller shall not be required to purchase such Mortgage Loan, if the Seller
delivers such documents 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
Seller in accordance with subsections 2.02(a) or (b) above or Section 2.03, the
Seller shall remit the applicable Purchase Price to the Master Servicer for
deposit in the Master Servicer Collection Account and shall provide written
notice to the Trustee detailing the components of the Purchase Price, signed by
a Servicing Officer. Upon deposit of the Purchase Price in the Master Servicer
Collection Account and upon receipt of a Request for Release with respect to
such Mortgage Loan, the Trustee or the Custodian will release to the Seller the
related Mortgage File and the Trustee shall execute and deliver all instruments
of transfer or assignment, without recourse, representation or warranty
furnished to it by the Seller, as are necessary to vest in the Seller title to
and rights under the Mortgage Loan. Such purchase shall be deemed to have
occurred on the date on which the deposit into the Master Servicer Collection
Account was made. The Trustee shall promptly notify the Rating Agencies of such
repurchase. The obligation of the Seller to cure, repurchase or substitute for
any Mortgage Loan as to which a defect in a constituent document exists shall be
the sole remedies respecting such defect available to the Certificateholders or
to the Trustee on their behalf.

                  (d) The Seller shall deliver to the Trustee, and Trustee
agrees to accept the Mortgage Note and other documents constituting the Mortgage
File with respect to any Replacement Mortgage Loan, which the Trustee or the
Custodian will review as provided in subsections 2.02(a) and 2.02(b), provided,
that the Closing Date referred to therein shall instead be the date of delivery
of the Mortgage File with respect to each Replacement Mortgage Loan.

         for Fannie Mae or Freddie Mac and is a mortgagee approved by the
         Secretary of Housing and Urban Development pursuant to sections 203 and
         211 of the National Housing Act.

                  (v) No litigation is pending or, to the best of its knowledge,
         threatened, against it that would materially and adversely affect the
         execution, delivery or enforceability of this Agreement or its ability
         to service the EMC Mortgage Loans or to perform any of its other
         obligations under this Agreement in accordance with the terms hereof.

                  (vi) No consent, approval, authorization or order of any court
         or governmental agency or body is required for its execution, delivery
         and performance of, or compliance with, this Agreement or the
         consummation of the transactions contemplated hereby, or if any such
         consent, approval, authorization or order is required, it has obtained
         the same.

                  (b) The Seller hereby represents and warrants to the
         Depositor, the Securities Administrator, the Master Servicer and the
         Trustee as follows, as of the Closing Date:

                  (i) The Seller is duly organized as a Delaware corporation and
         is validly existing and in good standing under the laws of the State of
         Delaware and is duly authorized and qualified to transact any and all
         business contemplated by this Agreement to be conducted by the Seller
         in any state in which a Mortgaged Property is located or is otherwise
         not required under applicable law to effect such qualification and, in
         any event, is in compliance with the doing business laws of any such
         state, to the extent necessary to ensure its ability to enforce each
         Mortgage Loan, to sell the Mortgage Loans in accordance with the terms

         this Agreement in accordance with the terms hereof.

                  (ii) The Seller has the full corporate power and authority to

         Agreement and has duly authorized by all necessary corporate action on

         execution and delivery hereof by the other parties hereto, constitutes
         a legal, valid and binding obligation of the Seller, enforceable
         against the Seller in accordance with its terms, except that (a) the
         enforceability hereof may be limited by bankruptcy, insolvency,
         moratorium, receivership and other similar laws relating to creditors'
         rights generally and (b) the remedy of specific performance and
         injunctive and other forms of equitable relief may be subject to
         equitable defenses and to the discretion of the court before which any
         proceeding therefor may be brought.

                  (iii) The execution and delivery of this Agreement by the
         Seller, the sale of the Mortgage Loans by the Seller under this
         Agreement, the consummation of any other of the transactions
         contemplated by this Agreement, and the fulfillment of or compliance
         with the terms hereof are in the ordinary course of business of the
         Seller and will not (A) result in a material breach of any term or
         provision of the charter or by-laws of the Seller or (B) materially
         conflict with, result in a material breach, violation or acceleration
         of, or result in a material default under, the terms of any other
         material agreement or instrument to which the Seller is a party or by
         which it may be bound, or (C) constitute a material violation of any
         statute, order or regulation applicable to the Seller of any court,
         regulatory body, administrative agency or governmental body having
         jurisdiction over the Seller; and the Seller is not in breach or
         violation of any material indenture or other material agreement or


                                      -46-

<PAGE>



         instrument, or in violation of any statute, order or regulation of any
         court, regulatory body, administrative agency or governmental body
         having jurisdiction over it which breach or violation may materially
         impair the Seller's ability to perform or meet any of its obligations
         under this Agreement.

                  (iv) The Seller is an approved seller of conventional mortgage
         loans for Fannie Mae or Freddie Mac and is a mortgagee approved by the
         Secretary of Housing and Urban Development pursuant to sections 203 and
         211 of the National Housing Act.

                  (v) No litigation is pending or, to the best of the Seller's
         knowledge, threatened, against the Seller that would materially and
         adversely affect the execution, delivery or enforceability of this
         Agreement or the ability of the Seller to sell the Mortgage Loans or to
         perform any of its other obligations under this Agreement in accordance
         with the terms hereof.

                  (vi) No consent, approval, authorization or order of any court
         or governmental agency or body is required for the execution, delivery
         and performance by the Seller of, or compliance by the Seller with,
         this Agreement or the consummation of the transactions contemplated
         hereby, or if any such consent, approval, authorization or order is
         required, the Seller has obtained the same.

                  (vii) With respect to each Mortgage Loan as of the Cut-off
         Date (unless otherwise expressly provided):

                  (A) The information set forth in the Mortgage Loan Schedule on
         the Closing Date is complete, true and correct.

                  (B) All payments required to be made prior to the Cut-off Date
         with respect to each Mortgage Loan have been made and no Mortgage Loan
         is delinquent sixty or more days; and the Seller has not advanced
         funds, or induced, solicited or knowingly received any advance of funds
         from a party other than the owner of the Mortgaged Property subject to
         the Mortgage, directly or indirectly, for the payment of any amount
         required under any Mortgage Loan.

                  (C) Except with respect to taxes, insurance and other amounts
         previously advanced by a prior servicer with respect to any Mortgage
         Loan, to the best of Seller's knowledge, there are no delinquent taxes,
         water charges, sewer rents, assessments, insurance premiums, leasehold
         payments, including assessments payable in future installments, or
         other outstanding charges affecting the related Mortgaged Property.

                  (D) The terms of the Mortgage Note and the Mortgage have not
         been impaired, waived, altered or modified in any respect, except by
         written instruments which in the case of the Mortgage Loans are in the
         Mortgage File and have been or will be recorded, if necessary to
         protect the interests of the Trustee, and which have been or will be
         delivered to the Trustee, all in accordance with this Agreement. The
         substance of any such waiver, alteration or modification has been
         approved by the title insurer, to the extent required by the related
         policy. No Mortgagor has been released, in whole or in part, except in
         connection with an assumption agreement approved by the title insurer,


                                      -47-

<PAGE>



to the extent required by the policy, and which assumption agreement in the case
of the Mortgage Loans is part of the Mortgage File.

                  (E) The Mortgage Note and the Mortgage are not subject to any
right of rescission, set-off, counterclaim or defense, including the defense of
usury, nor will the operation of any of the terms of the Mortgage Note and the
Mortgage, or the exercise of any right thereunder, render the Mortgage
unenforceable, in whole or in part, or subject to any right of rescission,
set-off, counterclaim or defense, including the defense of usury and no such
right of rescission, set-off, counterclaim or defense has been asserted with
respect thereto.

                  (F) All buildings upon, or comprising part of, the Mortgaged
Property are insured by an insurer acceptable to Fannie Mae and Freddie Mac
against loss by fire, hazards of extended coverage and such other hazards as are
customary in the area where the Mortgaged Property is located, and such insurer
is licensed to do business in the state where the Mortgaged Property is located.
All such insurance policies contain a standard mortgagee clause naming the
originator, its successors and assigns as mortgagee and Seller has received no
notice that all premiums thereon have not been paid. If upon origination of the
Mortgage Loan, the Mortgaged Property was, or was subsequently deemed to be, in
an area identified in the Federal Register by the Federal Emergency Management
Agency as having special flood hazards (and such flood insurance has been made
available), which require under applicable law that a flood insurance policy
meeting the requirements of the current guidelines of the Federal Insurance
Administration (or any successor thereto) be obtained, such flood insurance
policy is in effect which policy is with a generally acceptable carrier in an
amount representing coverage not less than the least of (A) the Stated Principal
Balance of the related Mortgage Loan, (B) the minimum amount required to
compensate for damage or loss on a replacement cost basis, or (C) the maximum
amount of insurance that is available under the Flood Disaster Protection Act of
1973. The Mortgage obligates the Mortgagor thereunder to maintain all such
insurance at Mortgagor's cost and expense and, on the Mortgagor's failure to do
so, authorizes the holder of the Mortgage to maintain such insurance at
Mortgagor's cost and expense and to obtain reimbursement therefor from the
Mortgagor.

                  (G) Any and all requirements of any federal, state or local
law including, usury, truth in lending, real estate settlement procedures
including, the Real Estate Settlement Procedures Act of 1974, as amended,
consumer credit protection, equal credit opportunity or disclosure laws
applicable to the Mortgage Loan have been complied with in all material
respects.

                  (H) The Mortgage has not been satisfied, canceled,
subordinated, or rescinded, in whole or in part, and the Mortgaged Property has
not been released from the lien of the Mortgage, in whole or in part, nor has
any instrument been executed that would effect any such release, cancellation,
subordination or rescission.

                  (I) The Mortgage is a valid, existing and enforceable first on
the Mortgaged Property, including all improvements on the Mortgaged Property, if
any, subject only to (1) the lien of current real property taxes and assessments
not yet due and payable, (2) covenants, conditions and restrictions, rights of
way, easements and other matters of the public record as of the date of
recording being acceptable to mortgage lending institutions generally and
specifically referred to in the lender's title insurance policy delivered to the
originator of the Mortgage Loan and which do not


                                      -48-

<PAGE>



adversely affect the Appraised Value of the Mortgaged Property and (3) other
matters to which like properties are commonly subject which do not materially
interfere with the benefits of the security intended to be provided by the
Mortgage. The Seller has full right to sell and assign the Mortgage to the
Depositor.

                  (J) The Mortgage Note and the related Mortgage are genuine and
each is the legal, valid and binding obligation of the maker thereof,
enforceable in accordance with its terms, except as the enforceability thereof
may be limited by bankruptcy, insolvency or reorganization or general principles
of equity.

                  (K) All parties to the Mortgage Note and the Mortgage had the
legal capacity to enter into the Mortgage Loan transaction and to execute and
deliver the Mortgage Note and the Mortgage, and the Mortgage Note and the
Mortgage have been duly and properly executed by such parties.

                  (L) The proceeds of the Mortgage Loan have been fully
disbursed and there is no requirement for future advances thereunder and any and
all requirements as to completion of any on- site or off-site improvement and as
to disbursements of any escrow funds therefor have been complied with. All
costs, fees and expenses incurred in making or closing the Mortgage Loan and the
recording of the Mortgage were paid, and the Mortgagor is not entitled to any
refund of any amounts paid or due under the Mortgage Note or Mortgage.

                  (M) Immediately prior to the conveyance of the Mortgage Loans
by the Seller to the Depositor hereunder, the Seller was the sole owner and
holder of the Mortgage Loan; the related Originator or the Seller or the
Servicer was the custodian of the related escrow account, if applicable; the
Mortgage Loan had neither been assigned nor pledged, and the Seller had good and
marketable title thereto, and had full right to transfer and sell the Mortgage
Loan and the related servicing rights to the Depositor free and clear of any
encumbrance, equity, lien, pledge, charge, claim or security interest subject to
the related Servicing Agreement, if applicable, and had full right and authority
subject to no interest or participation of, or agreement with, any other party,
to sell and assign the Mortgage Loan and the related servicing rights to the
Depositor pursuant to the terms of this Agreement.

                  (N) All parties which have had any interest in the Mortgage,
whether as mortgagee, assignee, pledgee or otherwise, are (or, during the period
in which they held and disposed of such interest, were) (1) in compliance with
any and all applicable licensing requirements of the laws of the state wherein
the Mortgaged Property is located, and (2) organized under the laws of such
state, qualified to do business in such state, a federal savings and loan
association or national bank having principal offices in such state or not
deemed to be doing business in such state under applicable law.

                  (O) The Mortgage Loan is covered by an ALTA lender's title
insurance policy or equivalent form acceptable to the Department of Housing and
Urban Development, or any successor thereto, and qualified to do business in the
jurisdiction where the Mortgaged Property is located, insuring (subject to the
exceptions contained in clause (I) above) the Seller (as assignee), its
successors and assigns as to the first priority lien of the Mortgage in the
original principal amount


                                      -49-

<PAGE>



of the Mortgage Loan and against any loss by reason of the invalidity or
unenforceability of the lien resulting from the provisions of the Mortgage Note
and/or Mortgage providing for adjustment in the Mortgage Rate and monthly
payment. Additionally, such lender's title insurance policy affirmatively
insures ingress and egress, and against encroachments by or upon the Mortgaged
Property or any interest therein. With respect to each Mortgage Loan, the Seller
(as assignee) is the sole insured of such lender's title insurance policy, and
such lender's title insurance policy is in full force and effect. No claims have
been made under such lender's title insurance policy, and no prior holder of the
related Mortgage, including the Seller in the case of a Mortgage Loan, has done,
by act or omission, anything which would impair the coverage of such lender's
title insurance policy. (P) Except as provided in clause (B), immediately prior
to the Cut-off Date, there was no default, breach, violation or event of
acceleration existing under the Mortgage or the Mortgage Note and there was no
event which, with the passage of time or with notice and the expiration of any
grace or cure period, would constitute a default, breach, violation or event of
acceleration, and the Seller has not waived any default, breach, violation or
event of acceleration.

                  (Q) There are no mechanics' or similar liens or claims which
have been filed for work, labor or material (and no rights are outstanding that
under law could give rise to such lien) affecting the related Mortgaged Property
which are or may be liens prior to or equal with, the lien of the related
Mortgage.

                  (R) All improvements which were considered in any appraisal
which was used in determining the Appraised Value of the related Mortgaged
Property lay wholly within the boundaries and building restriction lines of the
Mortgaged Property, and no improvements on adjoining properties encroach upon
the Mortgaged Property.

                  (S) [Reserved]

                  (T) The origination, servicing and collection practices with
respect to each Mortgage Note and Mortgage including, the establishment,
maintenance and servicing of the escrow accounts and escrow payments, if any,
since origination, have been conducted in all respects in accordance with the
terms of Mortgage Note and in compliance with all applicable laws and
regulations and, unless otherwise required by law or Fannie Mae/Freddie Mac
standard, in accordance with the proper, prudent and customary practices in the
mortgage origination and servicing business. With respect to the escrow accounts
and escrow payments, if any, and any EMC Mortgage Loan all such payments are in
the possession or under the control of the Seller and there exists no
deficiencies in connection therewith for which customary arrangements for
repayment thereof have not been made. Any interest required to be paid pursuant
to state and local law has been properly paid and credited.

                  (U) The Mortgaged Property is free of material damage and
waste and there is no proceeding pending for the total or partial condemnation
thereof.

                  (V) The Mortgage contains customary and enforceable provisions
to render the rights and remedies of the holder thereof adequate for the
realization against the Mortgaged Property of the benefits of the security
intended to be provided thereby, including, (1) in the case of a Mortgage
designated as a deed of trust, by trustee's sale, and (2) otherwise by judicial
foreclosure.


                                      -50-

<PAGE>



There is no other exemption available to the Mortgagor which would interfere
with the right to sell the Mortgaged Property at a trustee's sale or the right
to foreclose the Mortgage. The Mortgagor has not notified the Seller and the
Seller has no knowledge of any relief requested or allowed to the Mortgagor
under the Relief Act.

                  (W) The Mortgage Note is not and has not been secured by any
collateral except the lien of the applicable Mortgage.

                  (X) [Reserved]

                  (Y) In the event the Mortgage constitutes a deed of trust, a
trustee, duly qualified under applicable law to serve as such, has been properly
designated and currently so serves and is named in the Mortgage, and no fees or
expenses are or will become payable by the Certificateholders to the trustee
under the deed of trust, except in connection with a trustee's sale after
default by the Mortgagor.

                  (Z) No Mortgage Loan contains a permanent or temporary
"buydown" provision. The Mortgage Loan is not a graduated payment mortgage loan.

                  (AA) The Mortgagor has received all disclosure materials
required by applicable law with respect to the making of the Mortgage Loan.

                  (BB) No Mortgage Loan was made in connection with the
construction or rehabilitation of a Mortgaged Property.

                  (CC) To the best of Seller's knowledge, the Mortgaged Property
is lawfully occupied under applicable law and all inspections, licenses and
certificates required to be made or issued with respect to all occupied portions
of the Mortgaged Property and, with respect to the use and occupancy of the
same, including but not limited to certificates of occupancy, have been made or
obtained from the appropriate authorities.

                  (DD) The assignment of Mortgage with respect to a Mortgage
Loan is in recordable form and is acceptable for recording under the laws of the
jurisdiction in which the Mortgaged Property is located.

                  (EE) [Reserved].

                  (FF) [Reserved].

                  (GG) The Mortgaged Property consists of a single parcel of
real property with or without a detached single family residence erected
thereon, or an individual condominium unit, or a 2-4 family dwelling, or an
individual unit in a planned unit development as defined by Fannie Mae or a
manufactured dwelling which conforms with Fannie Mae and Freddie Mac
requirements regarding such dwellings, or a townhouse, each structure of which
is permanently affixed to the Mortgaged Property, and is legally classified as
real estate.

<PAGE>



                  (HH) [Reserved]

                  (II) [Reserved]

                  (JJ) Each Mortgage Loan at the time of origination was
underwritten in general in accordance with guidelines not inconsistent with the
guidelines set forth in the Prospectus Supplement and generally accepted prime
credit underwriting guidelines.

                  (KK) No error, omission, misrepresentation, fraud or similar
occurrence with respect to a Mortgage Loan has taken place on the part of the
Seller or the related Originator.

                  (LL) None of the Mortgage Loans are (a) loans subject to 12
CFR Part 226.31, 12 CFR Part 226.32 or 12 CFR Part 226.34 of Regulation Z, the
regulation implementing TILA, which implements HOEPA or (b) classified and/or
defined as a "high cost home loan" under any state or federal law, including,
but not limited to, the States of Georgia or North Carolina, or the laws of the
City of New York.

                  (c) Upon discovery by any of the parties hereto of a breach of
a representation or warranty set forth in Section 2.03(b)(vii) that materially
and adversely affects the interests of the Certificateholders in any Mortgage
Loan, the party discovering such breach shall give prompt written notice thereof
to the other parties. Any breach of a representation or warranty contained in
clause (LL) above, shall be automatically deemed to affect materially and
adversely the interests of the Certificateholders. The Seller hereby covenants
with respect to the representations and warranties set forth in Section
2.03(b)(vii), that within 90 days of the discovery of a breach of any
representation or warranty set forth therein that materially and adversely
affects the interests of the Certificateholders in any Mortgage Loan, it shall
cure such breach in all material respects and, if such breach is not so cured,
(i) if such 90-day period expires prior to the second anniversary of the Closing
Date, remove such Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund
and substitute in its place a Replacement Mortgage Loan, in the manner and
subject to the conditions set forth in this Section; or (ii) repurchase the
affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price
in the manner set forth below; provided that any such substitution pursuant to
(i) above or repurchase pursuant to (ii) above shall not be effected prior to
the delivery to the Trustee of an Opinion of Counsel if required by Section 2.05
hereof and any such substitution pursuant to (i) above shall not be effected
prior to the additional delivery to the Trustee of a Request for Release. The
Seller shall promptly reimburse the Master Servicer and the Trustee for any
expenses reasonably incurred by the Master Servicer or the Trustee in respect of
enforcing the remedies for such breach. To enable the Securities Administrator
to amend the Mortgage Loan Schedule, the Seller shall, unless it cures such
breach in a timely fashion pursuant to this Section 2.03, promptly notify the
Securities Administrator whether it intends either to repurchase, or to
substitute for, the Mortgage Loan affected by such breach. With respect to the
representations and warranties in Section 2.03(b)(vii) that are made to the best
of the Seller's knowledge, if it is discovered by any of the Depositor, the
Master Servicer, the Seller, the Securities Administrator or the Trustee that
the substance of such representation and warranty is inaccurate and such
inaccuracy materially and adversely affects the value of the related Mortgage
Loan, notwithstanding the Seller's lack of knowledge with respect to the
substance of such representation or warranty, the Seller shall


                                      -52-

<PAGE>



nevertheless be required to cure, substitute for or repurchase the affected
Mortgage Loan in accordance with the foregoing.

                  With respect to any Replacement Mortgage Loan or Loans, the
Seller shall deliver to the Trustee for the benefit of the Certificateholders
such documents and agreements as are required by Section 2.01. No substitution
will be made in any calendar month after the Determination Date for such month.
Scheduled Payments due with respect to Replacement Mortgage Loans in the Due
Period related to the Distribution Date on which such proceeds are to be
distributed shall not be part of the Trust Fund and will be retained by the
Seller. For the month of substitution, distributions to Certificateholders will
include the Scheduled Payment due on any Deleted Mortgage Loan for the related
Due Period and thereafter the Seller shall be entitled to retain all amounts
received in respect of such Deleted Mortgage Loan. The Securities Administrator
shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders
to reflect the removal of such Deleted Mortgage Loan and the substitution of the
Replacement Mortgage Loan or Loans and the Securities Administrator shall
deliver the amended Mortgage Loan Schedule to the Trustee and the Custodian.
Upon such substitution, the Replacement Mortgage Loan or Loans shall be subject
to the terms of this Agreement in all respects, and the Seller shall be deemed
to have made with respect to such Replacement Mortgage Loan or Loans, as of the
date of substitution, the representations and warranties set forth in Section
2.03(b)(vii) with respect to such Mortgage Loan. Upon any such substitution and
the deposit into the Master Servicer Collection Account of the amount required
to be deposited therein in connection with such substitution as described in the
following paragraph and receipt by the Trustee of a Request for Release for such
Mortgage Loan, the Trustee or the Custodian shall release to the Seller the
Mortgage File relating to such Deleted Mortgage Loan and held for the benefit of
the Certificateholders and the Trustee shall execute and deliver at the Seller's
direction such instruments of transfer or assignment as have been prepared by
the Seller, in each case without recourse, representation or warranty as shall
be necessary to vest in the Seller, or its respective designee, title to the
Trustee's interest in any Deleted Mortgage Loan substituted for pursuant to this
Section 2.03.

                  For any month in which the Seller substitutes one or more
Replacement Mortgage Loans for a Deleted Mortgage Loan, the Master Servicer will
determine the amount (if any) by which the aggregate principal balance of all
the Replacement Mortgage Loans as of the date of substitution is less than the
Stated Principal Balance (after application of the principal portion of the
Scheduled Payment due in the month of substitution) of such Deleted Mortgage
Loan. An amount equal to the aggregate of such deficiencies, described in the
preceding sentence for any Distribution Date (such amount, the "Substitution
Adjustment Amount") shall be deposited into the Master Servicer Collection
Account, by the Seller delivering such Replacement Mortgage Loan on the
Determination Date for the Distribution Date relating to the Prepayment Period
during which the related Mortgage Loan became required to be purchased or
replaced hereunder.

                  In the event that the Seller shall have repurchased a Mortgage
Loan, the Purchase Price therefor shall be deposited into the Master Servicer
Collection Account maintained by the Master Servicer, on the Determination Date
for the Distribution Date in the month following the month during which the
Seller became obligated to repurchase or replace such Mortgage Loan and upon
such deposit of the Purchase Price, the delivery of an Opinion of Counsel if
required by Section 2.05 and the receipt of a Request for Release, the Trustee
or the Custodian shall release the related

Mortgage File held for the benefit of the Certificateholders to the Seller, and
the Trustee shall execute and deliver at such Person's direction the related
instruments of transfer or assignment prepared by the Seller, in each case
without recourse, representation or warranty as shall be necessary to transfer
title from the Trustee for the benefit of the Certificateholders and transfer
the Trustee's interest to the Seller to any Mortgage Loan purchased pursuant to
this Section 2.03. It is understood and agreed that the obligation under this
Agreement of the Seller to cure, repurchase or replace any Mortgage Loan as to
which a breach has occurred and is continuing shall constitute the sole remedies
against the Seller respecting such breach available to Certificateholders, the
Depositor or the Trustee.

                  (d) The representations and warranties set forth in Section
2.03 hereof shall survive delivery of the respective Mortgage Loans and Mortgage
Files to the Trustee or the Custodian for the benefit of the Certificateholders.

         Section 2.04      REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR.

                  The Depositor hereby represents and warrants to the Master
Servicer, the Securities Administrator and the Trustee as follows, as of the
date hereof and as of the Closing Date:

                  (i) The Depositor is duly organized and is validly existing as
         a corporation in good standing under the laws of the State of Delaware
         and has full power and authority (corporate and other) necessary to own
         or hold its properties and to conduct its business as now conducted by
         it and to enter into and perform its obligations under this Agreement.

                  (ii) The Depositor has the full corporate power and authority
         to execute, deliver and perform, and to enter into and consummate the
         transactions contemplated by, this Agreement and has duly authorized,
         by all necessary corporate action on its part, the execution, delivery
         and performance of this Agreement; and this Agreement, assuming the due
         authorization, execution and delivery hereof by the other parties
         hereto, constitutes a legal, valid and binding obligation of the
         Depositor, enforceable against the Depositor in accordance with its
         terms, subject, as to enforceability, to (i) bankruptcy, insolvency,
         reorganization, moratorium and other similar laws affecting creditors'
         rights generally and (ii) general principles of equity, regardless of
         whether enforcement is sought in a proceeding in equity or at law.

                  (iii) The execution and delivery of this Agreement by the
         Depositor, the consummation of the transactions contemplated by this
         Agreement, and the fulfillment of or compliance with the terms hereof
         are in the ordinary course of business of the Depositor and will not
         (A) result in a material breach of any term or provision of the charter
         or by-laws of the Depositor or (B) materially conflict with, result in
         a material breach, violation or acceleration of, or result in a
         material default under, the terms of any other material agreement or
         instrument to which the Depositor is a party or by which it may be
         bound or (C) constitute a material violation of any statute, order or
         regulation applicable to the Depositor of any court, regulatory body,
         administrative agency or governmental body having jurisdiction over the
         Depositor; and the Depositor is not in breach or violation of any
         material indenture or other material agreement or instrument, or in
         violation of any statute, order or regulation of any court, regulatory
         body, administrative agency or governmental body having


                                      -54-

<PAGE>



         jurisdiction over it which breach or violation may materially impair
         the Depositor's ability to perform or meet any of its obligations under
         this Agreement.

                  (iv) No litigation is pending, or, to the best of the
         Depositor's knowledge, threatened, against the Depositor that would
         materially and adversely affect the execution, delivery or
         enforceability of this Agreement or the ability of the Depositor to
         perform its obligations under this Agreement in accordance with the
         terms hereof.

                  (v) No consent, approval, authorization or order of any court
         or governmental agency or body is required for the execution, delivery
         and performance by the Depositor of, or compliance by the Depositor
         with, this Agreement or the consummation of the transactions
         contemplated hereby, or if any such consent, approval, authorization or
         order is required, the Depositor has obtained the same.

                  The Depositor hereby represents and warrants to the Trustee as
of the Closing Date, following the transfer of the Mortgage Loans to it by the
Seller, the Depositor had good title to the Mortgage Loans and the related
Mortgage Notes were subject to no offsets, claims, defenses or counterclaims.

                  It is understood and agreed that the representations and
warranties set forth in the immediately preceding paragraph shall survive
delivery of the Mortgage Files to the Trustee or the Custodian for the benefit
of the Certificateholders. Upon discovery by the Depositor or the Trustee of a
breach of such representations and warranties, the party discovering such breach
shall give prompt written notice to the others and to each Rating Agency.

         Section 2.05      DELIVERY OF OPINION OF COUNSEL IN CONNECTION WITH
                           SUBSTITUTIONS AND REPURCHASES.

                  (a) Notwithstanding any contrary provision of this Agreement,
with respect to any Mortgage Loan that is not in default or as to which default
is not imminent, no repurchase or substitution pursuant to Sections 2.02 or 2.03
shall be made unless the Seller delivers to the Trustee an Opinion of Counsel,
addressed to the Trustee, to the effect that such repurchase or substitution
would not (i) result in the imposition of the tax on "prohibited transactions"
of REMIC I, REMIC II or REMIC III or contributions after the Closing Date, as
defined in sections 860F(a)(2) and 860G(d) of the Code, respectively or (ii)
cause any of REMIC I, REMIC II or REMIC III to fail to qualify as a REMIC at any
time that any Certificates are outstanding. Any Mortgage Loan as to which
repurchase or substitution was delayed pursuant to this paragraph shall be
repurchased or the substitution therefor shall occur (subject to compliance with
Sections 2.02 or 2.03) upon the earlier of (a) the occurrence of a default or
imminent default with respect to such Mortgage Loan and (b) receipt by the
Trustee of an Opinion of Counsel addressed to the Trustee to the effect that
such repurchase or substitution, as applicable, will not result in the events
described in clause (i) or clause (ii) of the preceding sentence.

                  (b) Upon discovery by the Depositor, the Seller or the Master
Servicer that any Mortgage Loan does not constitute a "qualified mortgage"
within the meaning of section 860G(a)(3) of the Code, the party discovering such
fact shall promptly (and in any event within 5 Business Days


                                      -55-

<PAGE>



of discovery) give written notice thereof to the other parties and the Trustee.
In connection therewith, the Trustee shall require the Seller, at the Seller's
option, to either (i) substitute, if the conditions in Section 2.03(c) with
respect to substitutions are satisfied, a Replacement Mortgage Loan for the
affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90
days of such discovery in the same manner as it would a Mortgage Loan for a
breach of representation or warranty contained in Section 2.03. The Trustee
shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto
(and the Custodian shall deliver the related Mortgage File) in the same manner,
and on the same terms and conditions, as it would a Mortgage Loan repurchased
for breach of a representation or warranty contained in Section 2.03.

         Section 2.06      COUNTERSIGNATURE AND DELIVERY OF CERTIFICATES.

                  The Trustee acknowledges the sale, transfer and assignment to
it of the Trust Fund and, concurrently with such transfer and assignment, has
executed, countersigned and delivered, to or upon the order of the Depositor,
the Certificates in authorized denominations evidencing the entire ownership of
the Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the
rights referred to above for the benefit of all present and future Holders of
the Certificates and to perform the duties set forth in this Agreement in
accordance with its terms.

                                   ARTICLE III

          ADMINISTRATION AND SERVICING OF EMC MORTGAGE LOANS BY COMPANY

         Section 3.01      THE COMPANY.

                  The Company shall service and administer the EMC Mortgage
Loans in accordance with customary and usual standards of practice of prudent
mortgage loan servicers in the respective states in which the related Mortgaged
Properties are located. In connection with such servicing and administration,
the Company shall have full power and authority, acting alone and/or through
subservicers as provided in Section 3.03, to do or cause to be done any and all
things that it may deem necessary or desirable in connection with such servicing
and administration, including but not limited to, the power and authority,
subject to the terms hereof (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 related Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages (but only
in the manner provided herein), (iii) to collect any Insurance Proceeds and
other Liquidation Proceeds, and (iv) subject to Section 3.09, to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any EMC Mortgage Loan; provided that the Company shall take no action
that is inconsistent with or prejudices the interests of the Trust Fund or the
Certificateholders in any EMC Mortgage Loan or the rights and interests of the
Depositor and the Trustee under this Agreement.

                  Without limiting the generality of the foregoing, the Company,
in its own name or in the name of the Trust, the Depositor or the Trustee, is
hereby authorized and empowered by the Trust, the Depositor and the Trustee,
when the Company believes it appropriate in its reasonable judgment, to execute
and deliver, on behalf of the Trustee, the Depositor, the Certificateholders or
any of them, any and all instruments of satisfaction or cancellation, or of
partial or full release or discharge and all other comparable instruments, with
respect to the EMC Mortgage Loans, and with respect to the related Mortgaged
Properties held for the benefit of the Certificateholders. The Company shall
prepare and deliver to the Depositor and/or the Trustee such documents requiring
execution and delivery by any or all of them as are necessary or appropriate to
enable the Company to service and administer the EMC Mortgage Loans. Upon
receipt of such documents, the Depositor and/or the Trustee shall execute such
documents and deliver them to the Company.

                  In accordance with the standards of the first paragraph of
this Section 3.01, the Company shall advance or cause to be advanced funds as
necessary for the purpose of effecting the payment of taxes and assessments on
the Mortgaged Properties relating to the EMC Mortgage Loans, which advances
shall be reimbursable in the first instance from related collections from the
Mortgagors pursuant to Section 5.03, and further as provided in Section 5.02.
All costs incurred by the Company, if any, in effecting the timely payments of
taxes and assessments on the Mortgaged Properties relating to the EMC Mortgage
Loans and related insurance premiums shall not, for the purpose of calculating
monthly distributions to the Certificateholders, be added to the Stated
Principal Balance under the related EMC Mortgage Loans, notwithstanding that the
terms of such Mortgage Loans so permit.

         Section 3.02      DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS.

                  (a) Except as otherwise provided in this Section 3.02, when
any property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Company shall to the extent that it has knowledge of such
conveyance, enforce any due-on-sale clause contained in any Mortgage Note or
Mortgage, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not adversely
affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Company is not required to exercise such
rights with respect to an EMC Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the
terms and conditions contained in the Mortgage Note and Mortgage related thereto
and the consent of the mortgagee under such Mortgage Note or Mortgage is not
otherwise so required under such Mortgage Note or Mortgage as a condition to
such transfer. In the event that the Company is prohibited by law from enforcing
any such due-on-sale clause, or if coverage under any Required Insurance Policy
would be adversely affected, or if nonenforcement is otherwise permitted
hereunder, the Company is authorized, subject to Section 3.02(b), to take or
enter into an assumption and modification agreement from or with the person to
whom such property has been or is about to be conveyed, pursuant to which such
person becomes liable under the Mortgage Note and, unless prohibited by
applicable state law, the Mortgagor remains liable thereon, provided that the
Mortgage Loan shall continue to be covered (if so covered before the Company
enters such agreement) by the applicable Required Insurance Policies. The
Company, subject to Section 3.02(b), is also authorized with the prior approval
of the insurers under any Required Insurance Policies to enter into a
substitution of liability agreement with such Person, pursuant to which the
original Mortgagor is released from liability and such Person is substituted as
Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the
foregoing, the Company shall not be deemed to be in default under this Section
3.02(a) by reason of any transfer or assumption that the Company reasonably
believes it is restricted by law from preventing.

                  (b) Subject to the Company's duty to enforce any due-on-sale
clause to the extent set forth in Section 3.02(a), in any case in which a
Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person
is to enter into an assumption agreement or modification agreement or supplement
to the Mortgage Note or Mortgage that requires the signature of the Trustee, or
if an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the related EMC Mortgage Loan, the Company shall
prepare and deliver or cause to be prepared and delivered to the Trustee for
signature and shall direct, in writing, the Trustee to execute the assumption
agreement with the Person to whom the Mortgaged Property is to be conveyed and
such modification agreement or supplement to the Mortgage Note or Mortgage or
other instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In connection with any such assumption, no material term of the Mortgage Note
(including, but not limited to, the Mortgage Rate, the amount of the Scheduled
Payment and any other term affecting the amount or timing of payment on the
Mortgage Loan) may be changed. In addition, the substitute Mortgagor and the
Mortgaged Property must be acceptable to the Company in accordance with its
servicing standards as then in effect. The Company shall notify the Trustee that
any such substitution or assumption agreement has been completed by forwarding
to the Trustee the original of such substitution or assumption agreement, which
in the case of the original shall be


                                      -58-

<PAGE>



added to the related Mortgage File and shall, for all purposes, be considered a
part of such Mortgage File to the same extent as all other documents and
instruments constituting a part thereof. Any fee collected by the Company for
entering into an assumption or substitution of liability agreement will be
retained by the Company as additional servicing compensation.

         Section 3.03      SUBSERVICERS.

                  The Company shall perform all of its servicing
responsibilities hereunder or may cause a subservicer to perform any such
servicing responsibilities on its behalf, but the use by the Company of a
subservicer shall not release the Company from any of its obligations hereunder
and the Company shall remain responsible hereunder for all acts and omissions of
each subservicer as fully as if such acts and omissions were those of the
Company. The Company shall pay all fees of each subservicer from its own funds,
and a subservicer's fee shall not exceed the Servicing Fee payable to the
Company hereunder.

                  At the cost and expense of the Company, without any right of
reimbursement from its Protected Account, the Company shall be entitled to
terminate the rights and responsibilities of a subservicer and arrange for any
servicing responsibilities to be performed by a successor subservicer; provided,
however, that nothing contained herein shall be deemed to prevent or prohibit
the Company, at the Company's option, from electing to service the related EMC
Mortgage Loans itself. In the event that the Company's responsibilities and
duties under this Agreement are terminated pursuant to Section 9.03, the Company
shall at its own cost and expense terminate the rights and responsibilities of
each subservicer effective as of the date of termination of the Company. The
Company shall pay all fees, expenses or penalties necessary in order to
terminate the rights and responsibilities of each subservicer from the Company's
own funds without reimbursement from the Trust Fund.

                  Notwithstanding the foregoing, the Company shall not be
relieved of its obligations hereunder and shall be obligated to the same extent
and under the same terms and conditions as if it alone were servicing and
administering the EMC Mortgage Loans. The Company shall be entitled to enter
into an agreement with a subservicer for indemnification of the Company by the
subservicer and nothing contained in this Agreement shall be deemed to limit or
modify such indemnification.

                  Any subservicing agreement and any other transactions or
services relating to the EMC Mortgage Loans involving a subservicer shall be
deemed to be between such subservicer and the Company alone, and neither the
Master Servicer nor the Trustee shall have any obligations, duties or
liabilities with respect to such subservicer including any obligation, duty or
liability of either the Master Servicer or the Trustee to pay such subservicer's
fees and expenses. For purposes of remittances to the Master Servicer pursuant
to this Agreement, the Company shall be deemed to have received a payment on an
EMC Mortgage Loan when a subservicer has received such payment.

                  Section 3.04 DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF
                               COMPANY TO BE HELD FOR TRUSTEE.

                  Notwithstanding any other provisions of this Agreement, the
Company shall transmit to the Trustee as required by this Agreement all
documents and instruments in respect of an EMC


                                      -59-

<PAGE>



Mortgage Loan coming into the possession of the Company from time to time and
shall account fully to the Trustee for any funds received by the Company or that
otherwise are collected by the Company as Liquidation Proceeds or Insurance
Proceeds in respect of any such Mortgage Loan. All Mortgage Files and funds
collected or held by, or under the control of, the Company in respect of any EMC
Mortgage Loans, whether from the collection of principal and interest payments
or from Liquidation Proceeds, including but not limited to, any funds on deposit
in the Protected Account maintained by the Company, shall be held by the Company
for and on behalf of the Trustee and shall be and remain the sole and exclusive
property of the Trustee, subject to the applicable provisions of this Agreement.
The Company also agrees that it shall not create, incur or subject any Mortgage
File or any funds that are deposited in the Protected Account maintained by the
Company or the Master Servicer Collection Account or in any Escrow Account, or
any funds that otherwise are or may become due or payable to the Trustee for the
benefit of the Certificateholders, to any claim, lien, security interest,
judgment, levy, writ of attachment or other encumbrance, or assert by legal
action or otherwise any claim or right of set off against any Mortgage File or
any funds collected on, or in connection with, an EMC Mortgage Loan, except,
however, that the Company shall be entitled to set off against and deduct from
any such funds any amounts that are properly due and payable to the Company
under this Agreement.

         Section 3.05      MAINTENANCE OF HAZARD INSURANCE.

                  The Company shall cause to be maintained, for each EMC
Mortgage Loan, hazard insurance on buildings upon, or comprising part of, the
Mortgaged Property against loss by fire, hazards of extended coverage and such
other hazards as are customary in the area where the related Mortgaged Property
is located with an insurer which is licensed to do business in the state where
the related Mortgaged Property is located. Each such policy of standard hazard
insurance shall contain, or have an accompanying endorsement that contains, a
standard mortgagee clause. The Company shall also cause flood insurance to be
maintained on property acquired upon foreclosure or deed in lieu of foreclosure
of any EMC Mortgage Loan, to the extent described below. Pursuant to Section
5.01, any amounts collected by the Company under any such policies (other than
the amounts to be applied to the restoration or repair of the related Mortgaged
Property or property thus acquired or amounts released to the Mortgagor in
accordance with the Company's normal servicing procedures) shall be deposited in
the Protected Account maintained by the Company. Any cost incurred by the
Company in maintaining any such insurance shall not, for the purpose of
calculating monthly distributions to the Certificateholders or remittances to
the Trustee for their benefit, be added to the principal balance of the Mortgage
Loan, notwithstanding that the terms of the EMC Mortgage Loan so permit. Such
costs shall be recoverable by the Company out of late payments by the related
Mortgagor or out of Liquidation Proceeds to the extent permitted by Section
5.02. It is understood and agreed that no earthquake or other additional
insurance is to be required of any Mortgagor or maintained on property acquired
in respect of a Mortgage other than pursuant to such applicable laws and
regulations as shall at any time be in force and as shall require such
additional insurance. If the Mortgaged Property is located at the time of
origination of the EMC Mortgage Loan in a federally designated special flood
hazard area and such area is participating in the national flood insurance
program, the Company shall cause flood insurance to be maintained with respect
to such Mortgage Loan. Such flood insurance shall be in an amount equal to the
least of (i) the Stated Principal Balance of the related Mortgage Loan, (ii)
minimum amount required to compensate for damage or


                                      -60-

<PAGE>



loss on a replacement cost basis or (iii) the maximum amount of such insurance
available for the related Mortgaged Property under the Flood Disaster Protection
Act of 1973, as amended.

                  In the event that the Company shall obtain and maintain a
blanket policy insuring against hazard losses on all of the Mortgage Loans, it
shall conclusively be deemed to have satisfied its obligations as set forth in
the first sentence of this Section 3.05, it being understood and agreed that
such policy may contain a deductible clause on terms substantially equivalent to
those commercially available and maintained by comparable servicers. If such
policy contains a deductible clause, the Company shall, in the event that there
shall not have been maintained on the related Mortgaged Property a policy
complying with the first sentence of this Section 3.05, and there shall have
been a loss that would have been covered by such policy, deposit in the
Protected Account maintained by the Company the amount not otherwise payable
under the blanket policy because of such deductible clause. Such deposit shall
be from the Company's own funds without reimbursement therefor. In connection
with its activities as administrator and servicer of the EMC Mortgage Loans, the
Company agrees to present, on behalf of itself, the Depositor and the Trustee
for the benefit of the Certificateholders, claims under any such blanket policy.

         Section 3.06      PRESENTMENT OF CLAIMS AND COLLECTION OF PROCEEDS.

                  The Company shall 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 Insurance
Policies. Any proceeds disbursed to the Company in respect of such Insurance
Policies shall be promptly deposited in the Protected Account maintained by the
Company 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 3.07    MAINTENANCE OF THE PRIMARY MORTGAGE INSURANCE POLICIES.

                  (a) The Company shall not take any action that would result in
noncoverage under any applicable Primary Mortgage Insurance Policy of any loss
which, but for the actions of the Company would have been covered thereunder.
The Company shall use its best efforts 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 EMC Mortgage Loan. The
Company shall not 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.

                  (b) The Company agrees 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 5.01, any amounts
collected by the Company under any Primary Mortgage Insurance Policies shall be
deposited in the Protected Account maintained by the Company, subject to
withdrawal pursuant to Section 5.02 hereof.

         Section 3.08      FIDELITY BOND, ERRORS AND OMISSIONS INSURANCE.

                  The Company shall maintain, at its own expense, a blanket
fidelity bond and an errors and omissions insurance policy, with broad coverage
with responsible companies on all officers, employees or other persons acting in
any capacity with regard to the EMC Mortgage Loans and who handle funds, money,
documents and papers relating to the EMC Mortgage Loans. The fidelity bond and
errors and omissions insurance shall be in the form of the Mortgage Banker's
Blanket Bond and shall protect and insure the Company against losses, including
forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of
such persons. Such fidelity bond shall also protect and insure the Company
against losses in connection with the failure to maintain any insurance policies
required pursuant to this Agreement and the release or satisfaction of an EMC
Mortgage Loan which is not in accordance with Accepted Servicing Practices. No
provision of this Section 3.08 requiring the fidelity bond and errors and
omissions insurance shall diminish or relieve the Company from its duties and
obligations as set forth in this Agreement. The minimum coverage under any such
bond and insurance policy shall be at least equal to the corresponding amounts
required by Accepted Servicing Practices. The Company shall deliver to the
Master Servicer a certificate from the surety and the insurer as to the
existence of the fidelity bond and errors and omissions insurance policy and
shall obtain a statement from the surety and the insurer that such fidelity bond
or insurance policy shall in no event be terminated or materially modified
without thirty days prior written notice to the Master Servicer and the Trustee.
The Company shall notify the Master Servicer and the Trustee within five
business days of receipt of notice that such fidelity bond or insurance policy
will be, or has been, materially modified or terminated. The Trustee for the
benefit of the Certificateholders must be named as loss payees on the fidelity
bond and as additional insured on the errors and omissions policy.

            Section 3.09 REALIZATION UPON DEFAULTED MORTGAGE LOANS;
                         DETERMINATION OF EXCESS LIQUIDATION PROCEEDS AND
                         REALIZED LOSSES; REPURCHASES OF CERTAIN MORTGAGE LOANS.

                  (a) The Company shall use reasonable efforts to foreclose upon
or otherwise comparably convert the ownership of properties securing such of the
EMC Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion, the Company shall follow
such practices and procedures as it shall deem necessary or advisable and as
shall be normal and usual in its general mortgage servicing activities and the
requirements of the insurer under any Required Insurance Policy; provided that
the Company shall not be required to expend its own funds in connection with any
foreclosure or towards the restoration of any property unless it shall determine
(i) that such restoration and/or foreclosure will increase the proceeds of
liquidation of the EMC Mortgage Loan after reimbursement to itself of such
expenses and (ii) that such expenses will be recoverable to it through Insurance
Proceeds or Liquidation Proceeds (respecting which it shall have priority for
purposes of withdrawals from the Protected Account maintained by the Company
pursuant to Section 5.02). If the Company reasonably believes that Liquidation
Proceeds with respect to any such Mortgage Loan would not be increased as a
result of such foreclosure or other action, such Mortgage Loan will be
charged-off and will become a Liquidated Loan. The Company will give notice of
any such charge-off to the Trustee and the Securities Administrator. The Company
shall be responsible for all other costs and expenses incurred by it in any such
proceedings; provided that


                                      -62-

<PAGE>



such costs and expenses shall be Servicing Advances and that it shall be
entitled to reimbursement thereof from the proceeds of liquidation of the
related Mortgaged Property, as contemplated in Section 5.02. If the Company has
knowledge that a Mortgaged Property that the Company is contemplating acquiring
in foreclosure or by deed- in-lieu of foreclosure is located within a one-mile
radius of any site with environmental or hazardous waste risks known to the
Company, the Company will, prior to acquiring the Mortgaged Property, consider
such risks and only take action in accordance with its established environmental
review procedures.

                  With respect to any REO Property, the deed or certificate of
sale shall be taken in the name of the Trustee for the benefit of the
Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's name shall be placed on the title to such REO
Property solely as the Trustee hereunder and not in its individual capacity. The
Company shall ensure that the title to such REO Property references this
Agreement and the Trustee's capacity hereunder. Pursuant to its efforts to sell
such REO Property, the Company shall either itself or through an agent selected
by the Company protect and conserve such REO Property in the same manner and to
such extent as is customary in the locality where such REO Property is located
and may, incident to its conservation and protection of the interests of the
Certificateholders, rent the same, or any part thereof, as the Company deems to
be in the best interest of the Company and the Certificateholders for the period
prior to the sale of such REO Property. The Company shall prepare for and
deliver to the Trustee and the Securities Administrator a statement with respect
to each REO Property that has been rented showing the aggregate rental income
received and all expenses incurred in connection with the management and
maintenance of such REO Property at such times as is necessary to enable the
Trustee to comply with the reporting requirements of the REMIC Provisions. The
net monthly rental income, if any, from such REO Property shall be deposited in
the Protected Account maintained by the Company no later than the close of
business on each Determination Date. The Company shall perform the tax reporting
and withholding related to foreclosures, abandonments and cancellation of
indebtedness income as specified by Sections 1445, 6050J and 6050P of the Code
by preparing and filing such tax and information returns, as may be required.

                  In the event that the Trust Fund acquires any Mortgaged
Property as aforesaid or otherwise in connection with a default or imminent
default on an EMC Mortgage Loan, the Company shall dispose of such Mortgaged
Property prior to three years after its acquisition by the Trust Fund or, at the
expense of the Trust Fund, request more than 60 days prior to the day on which
such three-year period would otherwise expire, an extension of the three-year
grace period unless the Trustee shall have been supplied with an Opinion of
Counsel addressed to the Trustee (such opinion not to be an expense of the
Trustee) to the effect that the holding by the Trust Fund of such Mortgaged
Property subsequent to such three-year period will not result in the imposition
of taxes on "prohibited transactions" of REMIC I, REMIC II or REMIC III as
defined in section 860F of the Code or cause either REMIC I, REMIC II or REMIC
III to fail to qualify as a REMIC at any time that any Certificates are
outstanding, in which case the Trust Fund may continue to hold such Mortgaged
Property (subject to any conditions contained in such Opinion of Counsel).
Notwithstanding any other provision of this Agreement, no Mortgaged Property
acquired by the Trust Fund shall be rented (or allowed to continue to be rented)
or otherwise used for the production of income by or on behalf of the Trust Fund
in such a manner or pursuant to any terms that would (i) cause such Mortgaged
Property to fail to qualify as "foreclosure property" within the meaning of
section 860G(a)(8) of the Code or (ii) subject any of REMIC I, REMIC II or REMIC
III to the


                                      -63-

<PAGE>



imposition of any federal, state or local income taxes on the income earned from
such Mortgaged Property under section 860G(c) of the Code or otherwise, unless
the Company has agreed to indemnify and hold harmless the Trust Fund with
respect to the imposition of any such taxes.

                  The decision of the Company to foreclose on a defaulted EMC
Mortgage Loan shall be subject to a determination by the Company that the
proceeds of such foreclosure would exceed the costs and expenses of bringing
such a proceeding. The income earned from the management of any Mortgaged
Properties acquired through foreclosure or other judicial proceeding, net of
reimbursement to the Company for expenses incurred (including any property or
other taxes) in connection with such management and net of unreimbursed
Servicing Fees, Advances, Servicing Advances and any management fee paid or to
be paid with respect to the management of such Mortgaged Property, shall be
applied to the payment of principal of, and interest on, the related defaulted
EMC Mortgage Loans (with interest accruing as though such Mortgage Loans were
still current) and all such income shall be deemed, for all purposes in the
Agreement, to be payments on account of principal and interest on the related
Mortgage Notes and shall be deposited into the Protected Account maintained by
the Company. To the extent the income received during a Prepayment Period is in
excess of the amount attributable to amortizing principal and accrued interest
at the related Mortgage Rate on the related EMC Mortgage Loan, such excess shall
be considered to be a partial Principal Prepayment for all purposes hereof.

                  The Liquidation Proceeds from any liquidation of a Mortgage
Loan, net of any payment to the Company as provided above, shall be deposited in
the Protected Account maintained by the Company on the next succeeding
Determination Date following receipt thereof for distribution on the related
Distribution Date, except that any Excess Liquidation Proceeds shall be retained
by the Company as additional servicing compensation.

                  The proceeds of any Liquidated Loan, as well as any recovery
resulting from a partial collection of Liquidation Proceeds or any income from
an REO Property, will be applied in the following order of priority: first, to
reimburse the Company for any related unreimbursed Servicing Advances and
Servicing Fees, pursuant to Section 5.02 or this Section 3.09; second, to
reimburse the Company for any unreimbursed Advances, pursuant to Section 5.02 or
this Section 3.09; third, to accrued and unpaid interest (to the extent no
Advance has been made for such amount) on the EMC Mortgage Loan or related REO
Property, at the Net Mortgage Rate to the first day of the month in which such
amounts are required to be distributed; and fourth, as a recovery of principal
of the Mortgage Loan.

                  (b) On each Determination Date, the Company shall determine
the respective aggregate amounts of Excess Liquidation Proceeds and Realized
Losses, if any, for the related Prepayment Period.

                  (c) The Company has no intent to foreclose on any EMC Mortgage
Loan based on the delinquency characteristics as of the Closing Date; provided,
that the foregoing does not prevent the Company from initiating foreclosure
proceedings on any date hereafter if the facts and circumstances of such
Mortgage Loans including delinquency characteristics in the Company's discretion
so warrant such action.

         Section 3.10      SERVICING COMPENSATION.

                  As compensation for its activities hereunder, the Company
shall be entitled to retain or withdraw from its Protected Account out of each
payment of interest on an EMC Mortgage Loan included in the Trust Fund an amount
equal to the Servicing Fee.

                  Additional servicing compensation in the form of any Excess
Liquidation Proceeds, assumption fees, late payment charges, all Prepayment
Interest Excess on any EMC Mortgage Loan, all income and gain net of any losses

Protected Account maintained by the Company shall be retained by the Company to
the extent not required to be deposited in the Protected Account maintained by

expenses incurred by it in connection with its servicing activities hereunder
(including payment of any premiums for hazard insurance, as required by Section
3.05 and maintenance of the other forms of insurance coverage required by
Section 3.07) and shall not be entitled to reimbursement therefor except as
specifically provided in Section 5.02.

         EMC will be entitled to retain any Prepayment Interest Excess pursuant
to Section 5.06(e).

         Section 3.11      REO PROPERTY.

                  (a) In the event the Trust Fund acquires ownership of any REO
Property in respect of any related EMC 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 Company shall sell any REO Property as expeditiously as
possible and in accordance with the provisions of this Agreement. Pursuant to
its efforts to sell such REO Property, the Company shall protect and conserve
such REO Property in the manner and to the extent required herein, in accordance
with the REMIC Provisions.

                  (b) The Company shall deposit all funds collected and received
in connection with the operation of any REO Property into the Protected Account
maintained by the Company.

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

         Section 3.12      LIQUIDATION REPORTS.

                  Upon the foreclosure of any Mortgaged Property relating to an
EMC Mortgage Loan or the acquisition thereof by the Trust Fund pursuant to a
deed-in-lieu of foreclosure, the Company shall submit a liquidation report to
the Master Servicer containing such information as shall be mutually acceptable
to the Company and the Master Servicer with respect to such Mortgaged Property.

         Section 3.13      ANNUAL CERTIFICATE AS TO COMPLIANCE.

                  (a) The Company will deliver to the Master Servicer not later
than March 1, 2004 and not later than March 1 of each year thereafter, a
certificate of a Servicing Officer stating, as to each signatory thereof, that
(i) a review of the activities of the Company during the preceding calendar year
and of performance under this Agreement has been made under such officers'
supervision, and (ii) to the best of such officers' knowledge, based on such
review, the Company has fulfilled all of its obligations under this Agreement
throughout such year, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officers and the
nature and status thereof except for such defaults as such officer in its good
faith judgment believe to be immaterial.

                  (b) (i) The Company will deliver to the Master Servicer, on or
before March 1 of each year beginning March 1, 2004 (or, if any such day is not
a Business Day, the immediately preceding Business Day), or on any alternative
date specified by the Master Servicer upon thirty (30) days written request, a
certification containing the information set forth in Exhibit L. Such
certification shall be signed by the senior officer in charge of servicing of
the Company. In addition, the Company shall provide such other information with
respect to the EMC Mortgage Loans and the servicing and administration thereof
within the control of the Company which shall be required to enable the Master
Servicer to comply with the reporting requirements of the Securities and
Exchange Act of 1934, as amended.

                           (ii) The Company shall indemnify and hold harmless
the Master Servicer
and its officers, directors, agents and affiliates from and against any losses,
damages, penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments and other costs and expenses arising out of or based upon a breach by
the Company or any of its officers, directors, agents or affiliates of its
obligations under this Section 3.13(b) or the Company's negligence, bad faith or
willful misconduct in connection therewith. If the indemnification provided for
herein is unavailable or insufficient to hold harmless the Master Servicer, then
the Company agrees that it shall contribute to the amount paid or payable by the
Master Servicer as a result of the losses, claims, damages or liabilities of the
Master Servicer in such proportion as is appropriate to reflect the relative
fault of the Master Servicer on the one hand and the Company on the other in
connection with a breach of the Company's obligations under this Section
3.13(b).

            Section 3.14 ANNUAL INDEPENDENT CERTIFIED PUBLIC
                         ACCOUNTANTS' SERVICING REPORT.

                  Not later than March 1, 2004 and not later than March 1 of
each year thereafter, the Company at its expense shall cause a firm of
independent public accountants which is a member of the American Institute of

examined certain documents and records relating to the Company's servicing of
mortgage loans of the same type as the EMC Mortgage Loans pursuant to servicing
agreements substantially similar to this Agreement, which agreements may include
this Agreement, and that, on the basis of such an examination, conducted
substantially in compliance with the Uniform Single Attestation Program for
Mortgage Bankers, such firm is of the opinion that the Company's servicing has
been conducted in compliance with the agreements examined pursuant to this
Section 3.14, except for (i) such exceptions as such


                                      -66-

maintain, a complete set of books and records for the EMC Mortgage Loans which
shall be appropriately identified in the Company's computer system to clearly

Company shall maintain in its possession, available for inspection by the Master
Servicer and the Trustee and shall deliver to Master Servicer and the Trustee

                                    SERVICER


       Section 4.01 MASTER SERVICER. The Master Servicer shall supervise,
monitor and oversee the obligation of the Company and the related Servicer to
service and administer their respective Mortgage Loans in accordance with the
terms of this Agreement and the related Servicing Agreement and shall have full
power and authority to do any and all things which it may deem necessary or
desirable in connection with such master servicing and administration. In
performing its obligations hereunder, the Master Servicer shall act in a manner
consistent with Accepted Master Servicing Practices. Furthermore, the Master
Servicer shall oversee and consult with the Company and the related Servicer as
necessary from time-to-time to carry out the Master Servicer's obligations
hereunder, shall receive, review and evaluate all reports, information and other
data provided to the Master Servicer by the Company and the related Servicer and
shall cause the Company and related Servicer to perform and observe the
covenants, obligations and conditions to be performed or observed by such Person
under this Agreement and the related Servicing Agreement. The Master Servicer
shall independently and separately monitor the Company and the related
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 Company's, the related Servicer's and Master Servicer's records, and based
on such reconciled and corrected information, prepare the statements specified
in Section 6.05 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 Company and the Servicer to the Protected Accounts
pursuant to this Agreement and the related Servicing Agreement.

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

Administrator 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 or the Securities Administrator; provided, however, that, unless
otherwise required by law, neither the Trustee nor the Securities Administrator
shall 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 and the Securities Administrator 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 or the
Securities Administrator's actual costs.

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

         Section 4.02 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 Company, the Servicers 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 addressed to the Trustee 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 4.03 MONITORING OF COMPANY AND SERVICER. (a) The Master
Servicer shall be responsible for reporting to the Trustee and the Seller the
compliance by the Company and the related Servicer with its duties under this
Agreement and the related Servicing Agreement. In the review of the Company's
and the related Servicer's activities, the Master Servicer may rely upon an
Officer's Certificate of the Company and the related Servicer with regard to
such Person's compliance with the terms of this Agreement or the related
Servicing Agreement. In the event that the Master Servicer, in its judgment,
determines that the Company or the related Servicer should be terminated in
accordance with this Agreement or the related Servicing Agreement, or that a
notice should be sent pursuant to this Agreement or the related 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 Company under this
Agreement and the related Servicer under the related Servicing Agreement, and
shall, in the event that the Company or the related Servicer fails to perform
its obligations in accordance with this Agreement or the related Servicing
Agreement, subject to the preceding paragraph, terminate the rights and
obligations of such Person 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 the related
Servicing Agreement and the pursuit of other appropriate remedies, shall be in
such form and carried out to such an extent and at such time as the Master
Servicer, in its good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Master Servicer shall pay the costs of such
enforcement at its own expense, subject to its right of


                                      -69-

<PAGE>



reimbursement pursuant to the provisions of this Agreement or the related
Servicing Agreement, 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 Company or the related Servicer, appointment
of a successor Servicer or the transfer and assumption of servicing by the
Master Servicer with respect to this Agreement or the related 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 Company or the related Servicer as a result of an
event of default by such Person and (ii) all costs and expenses associated with
the complete transfer of servicing, including all servicing files and all
servicing data and the completion, correction or manipulation of such servicing
data as may be required by the successor servicer to correct any errors or
insufficiencies in the servicing data or otherwise to enable the successor
service to service the Mortgage Loans in accordance with this Agreement or the
related Servicing Agreement) are not fully and timely reimbursed by the Company
or the terminated Servicer, the Master Servicer shall be entitled to
reimbursement of such costs and expenses from the Master Servicer Collection
Account.

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

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

         Section 4.04 FIDELITY BOND. The Master Servicer, at its expense, shall
maintain in effect a blanket fidelity bond and an errors and omissions insurance
policy, affording coverage with respect to all directors, officers, employees
and other Persons acting on such Master Servicer's behalf, and covering errors
and omissions in the performance of the Master Servicer's obligations hereunder.
The errors and omissions insurance policy and the fidelity bond shall be in such
form and amount generally acceptable for entities serving as master servicers or
trustees.

         Section 4.05 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 XI 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 4.03, shall not permit the Company or the related
Servicer to) knowingly or intentionally take any action, or fail to take (or
fail to cause to be taken) any action


                                      -70-

<PAGE>



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, REMIC II or REMIC III 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, REMIC II or REMIC III to
fail to qualify as a REMIC or result in the imposition of a tax upon REMIC I,
REMIC II or REMIC III, 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, the Company or the related Servicer to
execute and deliver instruments of satisfaction or cancellation, or of partial
or full release or discharge, and to foreclose upon or otherwise liquidate
Mortgaged Property, and to appeal, prosecute or defend in any court action
relating to the Mortgage Loans or the Mortgaged Property, in accordance with the
related 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, the Company or the related
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 10.11 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 4.06 DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS. To the extent
provided in this Agreement or the related Servicing Agreement, to the extent
Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer
shall cause the Company and the related Servicer to enforce such clauses in
accordance with this Agreement or the related Servicing Agreement. If applicable
law prohibits the enforcement of a due-on-sale clause or such clause is
otherwise not enforced in accordance with this Agreement or the related
Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the
original Mortgagor may be released from liability in accordance with this
Agreement or the related Servicing Agreement.

         Section 4.07 RELEASE OF MORTGAGE FILES. (a) Upon becoming aware of the
payment in full of any Mortgage Loan, or the receipt by the Company or the
related 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 Company or the related Servicer will, if required under
the related Servicing Agreement (or if the Company or the related Servicer does
not, the Master Servicer may), promptly furnish to the Custodian, on behalf of
the Trustee, two copies of a certification substantially in the form of Exhibit
H 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

related 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 Company or the related 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 Company or the
related Servicer and the Trustee and Custodian shall have no further
responsibility with regard to such Mortgage File. Upon any such payment in full,
the Company or the related 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,
representation or warranty) 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 this Agreement or the
related Servicing Agreement, the Trustee shall execute such documents as shall
be prepared and furnished to the Trustee by the Company, the related 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 Company, the related 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 H (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
Company, the related Servicer or the Master Servicer, as applicable. Such trust
receipt shall obligate the Company, the related Servicer or the Master Servicer
to return the Mortgage File to the Custodian on behalf of the Trustee, when the
need therefor by such Person 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 Company, the related Servicer or
the Master Servicer.

Agreement or the related Servicing Agreement. The Master Servicer shall, and (to
the extent provided in this Agreement or the related Servicing Agreement) shall
cause the Company and the related Servicer to, provide access to information and

Master Servicer or such Servicer under this Agreement or the related Servicing
Agreement.

            Section 4.09 STANDARD HAZARD INSURANCE AND FLOOD INSURANCE
                         POLICIES.

obligation of the Company and the related Servicer under this Agreement or the
related Servicing Agreement to maintain or cause to be maintained standard fire
and casualty insurance and, where applicable, flood insurance, all in accordance
with the provisions of this Agreement or the related Servicing Agreement. It is
understood and agreed that such insurance shall be with insurers meeting the
eligibility requirements set forth in this Agreement and the related 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 Sections 5.01, 5.03 and 5.04 any amounts collected by
the Company, the Servicers or the Master Servicer, or by the Company or the
Servicers, 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 this Agreement or the Servicing
Agreements) shall be deposited by the Company in its Protected Account or by the
related Servicer or the Master Servicer into the Master Servicer Collection
Account, subject to withdrawal pursuant to Sections 5.02, 5.03, 5.04 and 5.06,
as applicable. Any cost incurred by the Master Servicer, the Company or the
related 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

Master Servicer shall (to the extent provided in this Agreement and the related
Servicing Agreement) cause the Company or 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 Company or the related Servicer and remitted to
the Master Servicer) in respect of such policies, bonds or contracts shall be
promptly deposited in the Master Servicer Collection Account upon receipt,
except that any amounts realized that are to be applied to the repair or
restoration of the related Mortgaged Property as a condition precedent to the
presentation of claims on the related Mortgage Loan to the insurer under any
applicable Insurance Policy need not be so deposited (or remitted).

                         POLICIES.

         (a) The Master Servicer shall not take, or permit the Company or the
related Servicer (to the extent such action is prohibited under this Agreement
or the related 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 the Master Servicer, the Company or the related
Servicer, would have been covered thereunder. The Master Servicer shall use its
best reasonable efforts to cause the Company and the related Servicer (to the
extent required under this Agreement and the related Servicing Agreement) to
keep in force and effect (to the extent that the Mortgage Loan requires the
Mortgagor to maintain such insurance), primary mortgage insurance applicable to
each Mortgage Loan (including any LPMI Policy) 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 Company or the related Servicer (to
the extent required under this Agreement or 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

Servicer (to the extent required under this Agreement and 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 Sections 5.01, 5.03 and 5.04, any amounts collected by the
Company or the related Servicer under any Primary Mortgage Insurance Policies
shall be deposited by the Company in its Protected Account or by the related
Servicer in the Master Servicer Collection Account, subject to withdrawal
pursuant to Section 5.03 or 5.04, as applicable.

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

Servicing Agreement.

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 Company or the related Servicer to protect and
conserve, such REO Property in the manner and to the extent required by this

Monthly Advances as well as any unpaid Servicing Fees may be reimbursed or paid,

other net amounts derived from such REO Property.

         (d) To the extent provided in this Agreement or 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 Company or the

the attention of such Servicing Officer to lead such Servicing Officer to
believe that the Company or any Servicer has failed to perform any of its
duties, responsibilities and obligations under this Agreement or the related
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

         (b) Copies of such statements shall be provided to any

         Section 4.19 EMC. On the Closing Date, EMC will receive from the

         Section 4.21      OPTIONAL PURCHASE OF CERTAIN MORTGAGE LOANS.

         With respect to any Mortgage Loans 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 any Mortgage Loan from the Trust
which becomes 90 days or more delinquent or becomes an REO Property 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.

         In addition, EMC shall, at its option, purchase any Mortgage Loan from
the Trust if the first Due Date for such Mortgage Loan is subsequent to the
Cut-off Date and the initial Monthly Payment is not made within thirty (30) days
of such Due Date. Such purchase shall be made at a price equal to the Repurchase
Price.

         If at any time EMC remits to the Master Servicer a payment for deposit
in the Master Servicer Collection Account covering the amount of the Repurchase
Price for such a Mortgage Loan, and EMC provides to the Trustee a certification
signed by a Servicing Officer stating that the amount of such payment has been
deposited in the Master Servicer Collection Account, then the Trustee shall
execute the assignment of such Mortgage Loan prepared and delivered to the
Trustee, at the request of EMC, without recourse, representation or warranty, 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.

         Section 5.01      COLLECTION OF MORTGAGE LOAN PAYMENTS; PROTECTED
                           ACCOUNT.

                  (a) The Company shall make reasonable efforts in accordance
         with customary and usual standards of practice of prudent mortgage
         lenders in the respective states in which the Mortgaged Properties are
         located to collect all payments called for under the terms and
         provisions of the Mortgage Loans to the extent such procedures shall be
         consistent with this Agreement and the terms and provisions of any
         related Required Insurance Policy. Consistent with the foregoing, the
         Company may in its discretion (i) waive any late payment charge and
         (ii) extend the due dates for payments due on a Mortgage Note for a
         period not greater than 125 days. In the event of any such arrangement,
         the Company shall make Advances on the related Mortgage Loan during the
         scheduled period in accordance with the amortization schedule of such
         Mortgage Loan without modification thereof by reason of such
         arrangements, and shall be entitled to reimbursement therefor in
         accordance with Section 6.01. The Company shall not be required to
         institute or join in litigation with respect to collection of any
         payment (whether under a Mortgage, Mortgage Note or otherwise or
         against any public or governmental authority with respect to a taking
         or condemnation) if it reasonably believes that enforcing the provision
         of the Mortgage or other instrument pursuant to which such payment is
         required is prohibited by applicable law. In addition, if (x) a
         Mortgage Loan is in default or default is imminent or (y) the Company
         delivers to the Trustee a certification addressed to the Trustee, based
         on the advice of counsel or certified public accountants, in either
         case, that have a national reputation with respect to taxation of
         REMICs, that a modification of such Mortgage Loan will not result in
         the imposition of taxes on or disqualify any of REMIC I, REMIC II or
         REMIC III, the Company may, (A) amend the related Mortgage Note to
         reduce the Mortgage Rate applicable thereto, provided that such reduced
         Mortgage Rate shall in no event be lower than 5.00% with respect to any
         Mortgage Loan and (B) amend any Mortgage Note to extend to the maturity
         thereof.

                  (b) The Company shall establish and maintain a Protected
         Account (which shall at all times be an Eligible Account) with a
         depository institution in the name of the Company for the benefit of
         the Trustee on behalf of the Certificateholders and designated
         "JPMorgan Chase Bank , in trust for registered holders of Bear Stearns
         Asset Backed Securities, Inc., Asset-Backed Certificates Series
         2003-AC4". The Company shall deposit or cause to be deposited into the
         Protected Account on a daily basis within one Business Day of receipt,
         except as otherwise specifically provided herein, the following
         payments and collections remitted by subservicers or received by it in
         respect of the EMC Mortgage Loans subsequent to the Cut-off Date (other
         than in respect of principal and interest due on the EMC Mortgage Loans
         on or before the Cut-off Date) and the following amounts required to be
         deposited hereunder:

                  (i) all payments on account of principal, including Principal
         Prepayments, on the EMC Mortgage Loans;

                  (ii) all payments on account of interest on the EMC Mortgage
         Loans net of the related Servicing Fee permitted under Section 3.10 and
         LPMI Fees, if any;

accounts (each, an "Escrow Account") and deposit and retain therein all
collections from the Mortgagors (or advances by the Company) for the payment of

may be determined to be overages, to pay interest, if required by law or the
terms of the related Mortgage or Mortgage Note, to such Mortgagors on balances
in the Escrow Account or to clear and terminate the Escrow Account at the

Escrow Account shall not be a part of the Trust Fund.

                           DISTRIBUTIONS AND ADVANCES

         Section 6.01      ADVANCES.

         (a) The Company shall make an Advance with respect to any EMC Mortgage
Loan and deposit such Advance in the Master Servicer Collection Account no later
than 1:00 p.m. Eastern time on the Remittance Date in immediately available
funds. The Master Servicer shall cause the related Servicer to remit any such
Advance required pursuant to the terms of the related Servicing Agreement. The
Company or the related Servicer, as applicable, shall be obligated to make any
such Advance only to the extent that such advance would not be a Nonrecoverable
Advance. If the Company or the related Servicer shall have determined that it
has made a Nonrecoverable Advance or that a proposed Advance or a lesser portion
of such Advance would constitute a Nonrecoverable Advance, the Company or the
related Servicer, as the case may be, 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 Depositor, the Master Servicer,
each Rating Agency and the Trustee an Officer's Certificate setting forth the
basis for such determination.

                  In lieu of making all or a portion of such Advance from its
own funds, the Company may (i) cause to be made an appropriate entry in its
records relating to the Protected Account that any Amounts Held for Future
Distribution has been used by the Company in discharge of its obligation to make
any such Advance and (ii) transfer such funds from the Protected Account to the
Distribution Account. Any funds so applied and transferred shall be replaced by
the Company by deposit in the Distribution Account, no later than the close of
business on the Remittance Date immediately preceding the Distribution Date on
which such funds are required to be distributed pursuant to this Agreement.

                  The Company shall be entitled to be reimbursed from the
Protected Account for all Advances of its own funds made pursuant to this
Section as provided in Section 5.02. The obligation to make 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 6.01.

         (b) If the Scheduled Payment on a Mortgage Loan that was due on a
related Due Date and is delinquent other than as a result of application of the
Relief Act and for which the Company or the related Servicer was required to
make an Advance pursuant to this Agreement or the related Servicing Agreement
exceeds the amount deposited in the Master Servicer Collection Account which
will be used for an Advance with respect to such Mortgage Loan, the Master
Servicer will deposit in the Master Servicer Collection Account not later than
the Distribution Account Deposit Date immediately preceding the related
Distribution Date an amount equal to such deficiency, net of the Servicing Fee
for such Mortgage Loan except to the extent the Master Servicer determines any
such Advance to be nonrecoverable from Liquidation Proceeds, Insurance Proceeds
or future payments on the Mortgage Loan for which such Advance was made. Subject
to the foregoing, the


                                      -90-

<PAGE>



Master Servicer shall continue to make such Advances through the date that the
Company or the related Servicer is required to do so under this Agreement or the
related Servicing Agreement, as applicable. If applicable, on the Distribution
Account Deposit Date, the Master Servicer shall present an Officer's Certificate
to the Trustee (i) stating that the Master Servicer elects not to make an
Advance in a stated amount and (ii) detailing the reason it deems the advance to
be nonrecoverable.

                  Subject to and in accordance with the provisions of Article IX
hereof, in the event the Master Servicer fails to make such Advance, then the
Trustee, as Successor Master Servicer, shall be obligated to make such Advance,
subject to the provisions of this Section 6.01.

         Section 6.02      COMPENSATING INTEREST PAYMENTS.

         (a) In the event that there is a Prepayment Interest Shortfall arising
from a voluntary Principal Prepayment in part or in full by the Mortgagor with
respect to any EMC Mortgage Loan, the Company shall, to the extent of the
Servicing Fee for such Distribution Date, deposit into the Master Servicer
Collection Account, as a reduction of the Servicing Fee for such Distribution
Date, no later than the close of business on the Remittance Date immediately
preceding such Distribution Date, an amount equal to the Prepayment Interest
Shortfall; and in case of such deposit, the Company shall not be entitled to any
recovery or reimbursement from the Depositor, the Trustee, the Seller, the
Securities Administrator, the Trust Fund or the Certificateholders.

         (b) The Master Servicer shall cause each Servicer under the related
Servicing Agreement to remit any required Compensating Interest Payments to the
Master Servicer Collection Account on the Remittance Date.

         (c) The Master Servicer shall be required to remit the amount of any
such Prepayment Interest Shortfalls, to the extent of amounts earned on
Permitted Investments in the Master Servicer Collection Account for such
Distribution Date, in the event the Company or the related Servicer is required
to make such payment but fails to do so.

         transactions," "contributions" or "net income from foreclosure
         property" or state or local income or franchise taxes.

                  The information pursuant to clauses (i), (ii), (iii) and (iv)

remaining after the distributions pursuant to clauses (i) through (iii) above.

                  On each Distribution Date, all amounts representing Prepayment
Charges in respect of the Mortgage Loans received during the related Prepayment
Period will be distributed by REMIC I to the Holders of REMIC I Regular Interest
LTI-P. The payment of the foregoing amounts to the Holders of REMIC I Regular
Interest LTI-P shall not reduce the Uncertificated Principal Balance thereof.

         Section 6.07      REMIC II ALLOCATIONS.

                  (a) On each Distribution Date, the Available Funds, in the
following order of priority and in accordance with the Remittance Report, shall
be distributed by REMIC II to REMIC III on account of the REMIC II Regular
Interests or withdrawn from the Distribution Account and distributed to the
Holders of the Class R-2 Certificates, as the case may be:

                  (i) first, to the Holders of REMIC II Regular Interest

remaining unpaid from previous Distribution Dates. Amounts payable as
Uncertificated Accrued Interest in respect of REMIC II Regular Interest LTII-ZZ
shall be reduced and deferred when the REMIC II Overcollateralized Amount is
less than the REMIC II Overcollateralization Target Amount, by the lesser of (x)
the amount of such difference and (y) the REMIC II Regular Interest LTII-ZZ

of REMIC Regular Interest LTII-A, REMIC II Regular Interest LTII-M1, REMIC II
Regular Interest LTII-M2, REMIC II Regular Interest LTII-BA and REMIC II Regular

                  (ii) second, to the Holders of REMIC II Regular Interests, in
an amount equal to the remainder of the Available Funds for such Distribution
Date after the distributions made pursuant to clause (i) above, allocated as
follows:

                  (a) to the Holders of REMIC II Regular Interest LTII-AA and
REMIC II Regular Interest LTII-P, 98.00% of such remainder (other than amounts
payable under clause (d) below), until the Uncertificated Principal Balance of
such REMIC II Regular Interest is reduced to zero,


                                      -99-

<PAGE>



provided, however, that the Uncertificated Principal Balance of REMIC II Regular
Interest LTII-P shall not be reduced until the Distribution Date in August 2008
or any Distribution Date thereafter, at which point such amount shall be
distributed to REMIC II Regular Interest LTII-P, until $100 has been distributed
pursuant to this clause;

                  (b) to the Holders of REMIC Regular Interest LTII-A1, REMIC II
Regular Interest LTII-M1, REMIC II Regular Interest LTII-M2, REMIC II Regular
Interest LTII-BA and REMIC II Regular Interest LTII-BB, 1.00% of such remainder

Uncertificated Principal Balances of such REMIC II Regular Interests are reduced
to zero;

                  (c) to the Holders of REMIC II Regular Interest LTII-ZZ, 1.00%
of such remainder (other than amounts payable under the proviso below), until
the Uncertificated Principal Balance of such REMIC II Regular Interest is
reduced to zero; then

                  (d) any remaining amount to the Holders of the Class R-2
Certificates; and

                  (iii) third, to REMIC II Regular Interest LTII-P, 100% of the
amount paid in respect of REMIC I Regular Interest LTI-P;

provided, however, that (i) 98.00% and (ii) 2.00% of any principal payments that
are attributable to an Overcollateralization Release Amount shall be allocated
to Holders of (i) REMIC II Regular Interest LTII-AA and REMIC II Regular
Interest LTII-P, in that order and (ii) REMIC II Regular Interest LTII-ZZ,
respectively; provided that REMIC II Regular Interest LTII-P shall not be
reduced until the Distribution Date in June 2008, at which point such amount
shall be distributed to REMIC II Regular Interest LTII-P, until $100 has been
distributed pursuant to this clause.

         Section 6.08      NET WAC RESERVE FUND.

         (a) The Trustee shall establish a Net WAC Reserve Fund on behalf of the
holders of the Offered Certificates (other than the Class A-IO Certificates).
The Net WAC Reserve Fund must be an Eligible Account. The Net WAC Reserve Fund
shall be entitled "Net WAC Reserve Fund, JPMorgan Chase Bank as Trustee for the
benefit of holders of Bear Stearns Asset Backed Securities, Inc., Asset-Backed
Certificates, Series 2003-AC4, Class A, Class M-1, Class M-2, Class BA and Class
BB". On the Closing Date, the Depositor will deposit, or cause to be deposited,
into the Net WAC Reserve Fund $5,000. On each Distribution Date as to which
there is a Net WAC Rate Carryover Amount payable to any Class of Certificates,
the Trustee shall deposit the amounts pursuant to paragraphs 5, 6, 7, and 8 of
clause THIRD of Section 6.04(a) into the Net WAC Reserve Fund and the Trustee
has been directed by the Class C Certificateholder to distribute such amounts to
the Holders of the Offered Certificates (other than the Class A-IO Certificates)
in the amounts and priorities set forth in clause THIRD of Section 6.04(a).

         (b) The Net WAC Reserve Fund is an "outside reserve fund" within the
meaning of Treasury Regulation ss.1.860G-2(h) and shall be an asset of the Trust
Fund but not an asset of any REMIC. The Trustee on behalf of the Trust shall be
the nominal owner of the Net WAC Reserve Fund. The Class C Certificateholders
shall be the beneficial owners of the Net WAC Reserve Fund,


                                      -100-

<PAGE>



subject to the power of the Trustee to transfer amounts under Section 6.04(a).
Amounts in the Net WAC Reserve Fund shall be held either uninvested in a trust
or deposit account of the Trustee with no liability for interest or other
compensation thereof or, at the direction of the Majority Class C
Certificateholder, be invested in Permitted Investments that mature no later
than the Business Day prior to the next succeeding Distribution Date. All net
income and gain from such investments shall be distributed to the Majority Class
C Certificateholder, not as a distribution in respect of any interest in any
REMIC, on such Distribution Date. All amounts earned on amounts on deposit in
the Net WAC Reserve Fund shall be taxable to the Majority Class C
Certificateholder. Any losses on such investments shall be deposited in the Net
WAC Reserve Fund by the Majority Class C Certificateholder out of its own funds
immediately as realized. In the event that the Majority Class C
Certificateholder shall fail to provide investment instructions to the Trustee,
the amounts on deposit in the Net WAC Reserve Fund shall be held uninvested.

         (c) For federal tax return and information reporting, the right of the
holders of the Offered Certificates (other than the Class A-IO Certificates) to
receive payments from the Net WAC Reserve Fund in respect of any Net WAC Rate
Carryover Amount shall be assigned a value of zero.

                  The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by an authorized officer. Certificates
bearing the manual or facsimile signatures of individuals who were, at the time
when such signatures were affixed, authorized to sign on behalf of the Trustee
shall bind the Trustee, notwithstanding that such individuals or any of them
have ceased to be so authorized prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of such authentication and
delivery. No Certificate shall be entitled to any benefit under this Agreement,
or be valid for any purpose, unless there appears on such Certificate the
countersignature of the Trustee by manual signature, and such countersignature
upon any Certificate shall be conclusive evidence, and the only evidence, that
such Certificate has been duly countersigned and delivered hereunder. All
Certificates shall be dated the date of their countersignature. On the Closing
Date, the Trustee shall authenticate the Certificates to be issued at the
written direction of the Depositor, or any affiliate thereof.

                  The Depositor shall provide, or cause to be provided, to the
Trustee on a continuous basis, an adequate inventory of Certificates to
facilitate transfers.

         Section 7.02      CERTIFICATE REGISTER; REGISTRATION OF TRANSFER AND
                           EXCHANGE OF CERTIFICATES.

                  (a) The Trustee shall maintain, or cause to be maintained in
accordance with the provisions of Section 7.09 hereof, a Certificate Register
for the Trust Fund in which, subject to the


                                      -102-

<PAGE>



provisions of subsections (b) and (c) below and to such reasonable regulations
as it may prescribe, the Trustee shall provide for the registration of
Certificates and of Transfers and exchanges of Certificates as herein provided.
Upon surrender for registration of Transfer of any Certificate, the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of the same Class and of like
aggregate Percentage Interest.

                  At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of the same Class in authorized denominations
and evidencing the same aggregate Percentage Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee. Whenever
any Certificates are so surrendered for exchange, the Trustee shall execute,
authenticate, and deliver the Certificates that the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
registration of Transfer or exchange shall be accompanied by a written
instrument of Transfer in form satisfactory to the Trustee duly executed by the
holder thereof or his attorney duly authorized in writing.

                  No service charge to the Certificateholders shall be made for
any registration of Transfer or exchange of Certificates, but 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 may be required.

                  All Certificates surrendered for registration of Transfer or
exchange shall be canceled and subsequently destroyed by the Trustee in
accordance with the Trustee's customary procedures.

                  (b) No Transfer of a Private Certificate shall be made unless
such Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a Transfer is to be made in reliance upon an exemption
from the Securities Act and such laws, in order to assure compliance with the
Securities Act and such laws, the Certificateholder desiring to effect such
Transfer and such Certificateholder's prospective transferee shall each certify
to the Trustee and the Securities Administrator in writing the facts surrounding
the Transfer in substantially the forms set forth in Exhibit E (the "Transferor
Certificate") and (x) deliver a letter in substantially the form of either
Exhibit F (the "Investment Letter") or Exhibit G (the "Rule 144A Letter") or (y)
there shall be delivered to the Trustee and the Securities Administrator an
Opinion of Counsel addressed to the Trustee and the Securities Administrator
that such Transfer may be made pursuant to an exemption from the Securities Act,
which Opinion of Counsel shall not be an expense of the Depositor, the Seller,
the Master Servicer, the Securities Administrator or the Trustee. The Depositor
shall provide to any Holder of a Private Certificate and any prospective
transferee designated by any such Holder, information regarding the related
Certificates and the Mortgage Loans and such other information as shall be
necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4)
for Transfer of any such Certificate without registration thereof under the
Securities Act pursuant to the registration exemption provided by Rule 144A. The
Trustee, the Securities Administrator and the Master Servicer shall cooperate
with the Depositor in providing the Rule 144A information referenced in the
preceding sentence, including providing to the Depositor such information
regarding the Certificates, the Mortgage Loans and other matters regarding the
Trust Fund as the Depositor shall reasonably request to meet its obligation
under the preceding sentence. Each Holder of a Private Certificate desiring to
effect such


                                      -103-

<PAGE>



Transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor,
the Seller, the Securities Administrator and the Master Servicer against any
liability that may result if the Transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No Transfer of an ERISA Restricted Certificate shall be made
unless either (i) the Trustee, the Master Servicer and the Securities
Administrator shall have received a representation from the transferee of such
Certificate acceptable to and in form and substance satisfactory to the Trustee,
the Master Servicer and the Securities Administrator, to the effect that such
transferee is not an employee benefit plan subject to Section 406 of ERISA
and/or a plan subject to Section 4975 of the Code, or a Person acting on behalf
of any such plan or using the assets of any such plan, or (ii) in the case of
any such ERISA Restricted Certificate presented for registration in the name of
an employee benefit plan subject to ERISA, or a plan subject to Section 4975 of
the Code (or comparable provisions of any subsequent enactments), or a trustee
of any such plan or any other person acting on behalf of any such plan, the
Trustee shall have received an Opinion of Counsel for the benefit of the
Trustee, the Master Servicer and the Securities Administrator and on which they
may rely, satisfactory to the Trustee, to the effect that the purchase and
holding of such ERISA Restricted Certificate will not constitute or result in
the assets of the Trust being deemed to be "plan assets" under ERISA or the
Code, will not result in any prohibited transactions under ERISA or Section 4975
of the Code and will not subject the Trustee, the Master Servicer, the Depositor
or the Securities Administrator to any obligation in addition to those expressly
undertaken in this Agreement, which Opinion of Counsel shall not be an expense
of the Trustee, the Master Servicer, the Depositor or the Securities
Administrator. Notwithstanding anything else to the contrary herein, any
purported transfer of an ERISA Restricted Certificate to or on behalf of an
employee benefit plan subject to Section 406 of ERISA and/or a plan subject to
Section 4975 of the Code without the delivery of the Opinion of Counsel as
described above shall be void and of no effect; provided that the restriction
set forth in this sentence shall not be applicable if there has been delivered
to the Trustee an Opinion of Counsel meeting the requirements of clause (ii) of
the first sentence of this paragraph. None of the Trustee, the Securities
Administrator or the Master Servicer shall be required to monitor, determine or
inquire as to compliance with the transfer restrictions with respect to any
ERISA Restricted Certificate that is a Book-Entry Certificate, and none of the
Trustee, the Securities Administrator or the Master Servicer shall have any
liability for transfers of any such Book-Entry Certificates made through the
book-entry facilities of any Depository or between or among participants of the
Depository or Certificate Owners made in violation of the transfer restrictions
set forth herein. None of the Trustee, the Securities Administrator or the
Master Servicer shall be under any liability to any Person for any registration
of transfer of any ERISA Restricted Certificate that is in fact not permitted by
this Section 7.02(b) or for making any payments due on such Certificate to the
Holder thereof or taking any other action with respect to such Holder under the
provisions of this Agreement. The Trustee and the Securities Administrator shall
each be entitled, but not obligated, to recover from any Holder of any ERISA
Restricted Certificate that was in fact an employee benefit plan subject to
Section 406 of ERISA or a plan subject to Section 4975 of the Code or a Person
acting on behalf of any such plan at the time it became a Holder or, at such
subsequent time as it became such a plan or Person acting on behalf of such a
plan, all payments made on such ERISA Restricted Certificate at and after either
such time. Any such payments so recovered by the Trustee or the Securities
Administrator shall be paid and delivered by the Trustee or the Securities
Administrator to the last preceding Holder of such Certificate that is not such
a plan or Person acting on behalf of a plan.

virtue of its acquisition or holding of that certificate or interest therein,
that either (i) it is not a Plan or investing with "Plan Assets", (ii) it has
acquired and is holding such certificate in reliance on the Exemption, and that
it understands that there are certain conditions to the availability of the
Exemption, including that the certificate must be rated, at the time of
purchase, not lower than "BBB-" (or its equivalent) by S&P, Fitch or Moody's
Investors Service, Inc., and the certificate is so rated or (iii) (1) it is an
insurance company, (2) the source of funds used to acquire or hold the
certificate or interest therein is an "insurance company general account," as
such term is defined in Prohibited Transaction Class Exemption ("PTCE") 95-60,
and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

                  (c) Each Person who has or who acquires any Ownership Interest
         in a Residual Certificate shall be deemed by the acceptance or
         acquisition of such Ownership Interest to have agreed to be bound by
         the following provisions, and the rights of each Person acquiring any
         Ownership Interest in a Residual Certificate are expressly subject to
         the following provisions:

                  (i) Each Person holding or acquiring any Ownership Interest in
         a Residual Certificate shall be a Permitted Transferee and shall
         promptly notify the Trustee of any change or impending change in its
         status as a Permitted Transferee.

                  (ii) No Ownership Interest in a Residual Certificate may be
         registered on the Closing Date or thereafter transferred, and the
         Trustee shall not register the Transfer of any Residual Certificate
         unless, in addition to the certificates required to be delivered to the
         Trustee under subparagraph (b) above, the Trustee shall have been
         furnished with an affidavit (a "Transfer Affidavit") of the initial
         owner or the proposed transferee in the form attached hereto as Exhibit
         D.

                  (iii) Each Person holding or acquiring any Ownership Interest
         in a Residual Certificate shall agree (A) to obtain a Transfer
         Affidavit from any other Person to whom such Person attempts to
         Transfer its Ownership Interest in a Residual Certificate, (B) to
         obtain a Transfer Affidavit from any Person for whom such Person is
         acting as nominee, trustee or agent in connection with any Transfer of
         a Residual Certificate and (C) not to Transfer its Ownership Interest
         in a Residual Certificate or to cause the Transfer of an Ownership
         Interest in a Residual Certificate to any other Person if it has actual
         knowledge that such Person is not a Permitted Transferee.

                  (iv) Any attempted or purported Transfer of any Ownership
         Interest in a Residual Certificate in violation of the provisions of
         this Section 7.02(c) shall be absolutely null and void and shall vest
         no rights in the purported Transferee. If any purported transferee
         shall become a Holder of a Residual Certificate in violation of the
         provisions of this Section 6.02(c), then the last preceding Permitted
         Transferee shall be restored to all rights as Holder thereof
         retroactive to the date of registration of Transfer of such Residual
         Certificate. The Trustee shall be under no liability to any Person for
         any registration of Transfer of a Residual Certificate that is in fact
         not permitted by Section 7.02(b) and this Section 7.02(c) or for making
         any payments due on such Certificate to the Holder thereof or taking
         any other action with respect to such Holder under the provisions of
         this Agreement so long as the Transfer


                                      -105-

<PAGE>



         was registered after receipt of the related Transfer Affidavit. The
         Trustee shall be entitled but not obligated to recover from any Holder
         of a Residual Certificate that was in fact not a Permitted Transferee
         at the time it became a Holder or, at such subsequent time as it became
         other than a Permitted Transferee, all payments made on such Residual
         Certificate at and after either such time. Any such payments so
         recovered by the Trustee shall be paid and delivered by the Trustee to
         the last preceding Permitted Transferee of such Certificate.

                  (v) The Master Servicer shall make available within 60 days of
         written request from the Trustee, all information necessary to compute
         any tax imposed under Section 860E(e) of the Code as a result of a
         Transfer of an Ownership Interest in a Residual Certificate to any
         Holder who is not a Permitted Transferee.

                  The restrictions on Transfers of a Residual Certificate set
forth in this Section 7.02(c) shall cease to apply (and the applicable portions
of the legend on a Residual Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel
addressed to the Trustee, which Opinion of Counsel shall not be an expense of
the Trustee, the Securities Administrator, the Seller or the Master Servicer to
the effect that the elimination of such restrictions will not cause REMIC I,
REMIC II and/or REMIC III, as applicable, to fail to qualify as a REMIC at any
time that the Certificates are outstanding or result in the imposition of any
tax on the Trust Fund, a Certificateholder or another Person. Each Person
holding or acquiring any ownership Interest in a Residual Certificate hereby
consents to any amendment of this Agreement that, based on an Opinion of Counsel
addressed to the Trustee and furnished to the Trustee, is reasonably necessary
(a) to ensure that the record ownership of, or any beneficial interest in, a
Residual Certificate is not transferred, directly or indirectly, to a Person
that is not a Permitted Transferee and (b) to provide for a means to compel the
Transfer of a Residual Certificate that is held by a Person that is not a
Permitted Transferee to a Holder that is a Permitted Transferee.

                  (d) The preparation and delivery of all certificates and
opinions referred to above in this Section 7.02 shall not be an expense of the
Trust Fund, the Trustee, the Depositor, the Seller, the Securities Administrator
or the Master Servicer.

         Section 7.03      MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

                  If (a) 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 of the ownership thereof and
(b) there is delivered to the Securities Administrator and the Trustee such
security or indemnity as may be required by them to save each of them harmless,
then, in the absence of notice to the Trustee that such Certificate has been
acquired by a bona fide purchaser, the Trustee shall execute, authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of like Class, tenor and Percentage
Interest. In connection with the issuance of any new Certificate under this
Section 7.03, 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 replacement Certificate issued pursuant to this Section 7.03
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. All Certificates surrendered to the


                                      -106-

<PAGE>



Trustee under the terms of this Section 7.03 shall be canceled and destroyed by
the Trustee in accordance with its standard procedures without liability on its
part.

         Section 7.04      PERSONS DEEMED OWNERS.

                  The Securities Administrator, the Trustee and any agent of the
Securities Administrator 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 as provided in this Agreement and for all other purposes
whatsoever, and neither the Securities Administrator, the Trustee nor any agent
of the Securities Administrator or the Trustee shall be affected by any notice
to the contrary.

         Section 7.05      ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND
                           ADDRESSES.

                  If three or more Certificateholders (a) request such
information in writing from the Trustee, (b) state that such Certificateholders
desire to communicate with other Certificateholders with respect to their rights
under this Agreement or under the Certificates, and (c) provide a copy of the
communication that such Certificateholders propose to transmit or if the
Depositor or the Master Servicer shall request such information in writing from
the Trustee, then the Trustee shall, within ten Business Days after the receipt
of such request, provide the Depositor, the Master Servicer or such
Certificateholders at such recipients' expense the most recent list of the
Certificateholders of the Trust Fund held by the Trustee, if any. The Depositor
and every Certificateholder, by receiving and holding a Certificate, agree that
the Trustee shall not be held accountable by reason of the disclosure of any
such information as to the list of the Certificateholders hereunder, regardless
of the source from which such information was derived.

         Section 7.06      BOOK-ENTRY CERTIFICATES.

                  The Regular Certificates, upon original issuance, shall be
issued in the form of one or more typewritten Certificates representing the
Book- Entry Certificates, to be delivered to the Depository by or on behalf of
the Depositor. Such Certificates shall initially be registered on the
Certificate Register in the name of the Depository or its nominee, and no
Certificate Owner of such Certificates will receive a definitive certificate
representing such Certificate Owner's interest in such Certificates, except as
provided in Section 7.08. Unless and until definitive, fully registered
Certificates ("Definitive Certificates") have been issued to the Certificate
Owners of such Certificates pursuant to Section 7.08:

                  (a) the provisions of this Section shall be in full force and
effect;

                  (b) the Depositor, the Securities Administrator and the
Trustee may deal with the Depository and the Depository Participants for all
purposes (including the making of distributions) as the authorized
representative of the respective Certificate Owners of such Certificates;

                  (c) registration of the Book-Entry Certificates may not be
transferred by the Trustee except to another Depository;



                                      -107-

<PAGE>



                  (d) the rights of the respective Certificate Owners of such
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of such Certificates and the Depository and/or the Depository
Participants. Pursuant to the Depository Agreement, unless and until Definitive
Certificates are issued pursuant to Section 7.08, the Depository will make
book-entry transfers among the Depository Participants and receive and transmit
distributions of principal and interest on the related Certificates to such
Depository Participants;

                  (e) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants;

                  (f) the Trustee may rely and shall be fully protected in
relying upon information furnished by the Depository with respect to its
Depository Participants; and

                  (g) to the extent that the provisions of this Section conflict
with any other provisions of this Agreement, the provisions of this Section
shall control.

                  For purposes of any provision of this Agreement requiring or
permitting actions with the consent of, or at the direction of,
Certificateholders evidencing a specified percentage of the aggregate unpaid
principal amount of any Class of Certificates, such direction or consent may be
given by Certificate Owners (acting through the Depository and the Depository
Participants) owning Book-Entry Certificates evidencing the requisite percentage
of principal amount of such Class of Certificates.

         Section 7.07      NOTICES TO DEPOSITORY.

                  Whenever any notice or other communication is required to be
given to Certificateholders of a Class with respect to which Book-Entry
Certificates have been issued, unless and until Definitive Certificates shall
have been issued to the related Certificate Owners, the Trustee shall give all
such notices and communications to the Depository.

         Section 7.08      DEFINITIVE CERTIFICATES.

                  If, after Book-Entry Certificates have been issued with
respect to any Certificates, (a) the Depositor or the Depository advises the
Trustee that the Depository is no longer willing or able to discharge properly
its responsibilities under the Depository Agreement with respect to such
Certificates and the Depositor is unable to locate a qualified successor, (b)
the Depositor, at its sole option, advises the Trustee that it elects to
terminate the book-entry system with respect to such Certificates through the
Depository or (c) after the occurrence and continuation of an Event of Default,
Certificate Owners of such Book-Entry Certificates having not less than 51% of
the Voting Rights evidenced by any Class of Book-Entry Certificates advise the
Trustee and the Depository in writing through the Depository Participants that
the continuation of a book-entry system with respect to Certificates of such
Class through the Depository (or its successor) is no longer in the best
interests of the Certificate Owners of such Class, then the Trustee shall notify
all Certificate Owners of such Certificates, through the Depository, of the
occurrence of any such event and of the availability of Definitive Certificates
to applicable Certificate Owners requesting the same. The


                                      -108-

Depositor shall provide the Trustee with an adequate inventory of certificates
to facilitate the issuance and transfer of Definitive Certificates. Upon
surrender to the Trustee of any such Certificates by the Depository, accompanied
by registration instructions from the Depository for registration, the Trustee
shall countersign and deliver such Definitive Certificates. Neither the
Depositor nor the Trustee shall be liable for any delay in delivery of such
instructions and each may conclusively rely on, and shall be protected in
relying on, such instructions. Upon the issuance of such Definitive
Certificates, all references herein to obligations imposed upon or to be
performed by the Depository shall be deemed to be imposed upon and performed by
the Trustee, to the extent applicable with respect to such Definitive
Certificates and the Trustee shall recognize the Holders of such Definitive
Certificates as Certificateholders hereunder.

         Section 7.09      MAINTENANCE OF OFFICE OR AGENCY.

                  The Trustee will maintain or cause to be maintained at its
expense an office or offices or agency or agencies at 2001 Bryan Street, 8th
Floor, Dallas, Texas 75201, Attention: ITS Transfer Department -BSABS 2003-AC4
where Certificates may be surrendered for registration of transfer or exchange.
The Trustee will give prompt written notice to the Certificateholders of any
change in such location of any such office or agency.

                       THE COMPANY AND THE MASTER SERVICER


         Section 8.01 LIABILITIES OF THE DEPOSITOR, THE COMPANY AND THE MASTER
SERVICER. Each of the Depositor, the Company and 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 8.02 MERGER OR CONSOLIDATION OF THE DEPOSITOR, THE COMPANY OR
THE MASTER SERVICER.

                  (a) Each of the Depositor, the Company and 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 Depositor, the Company or the
Master Servicer may be merged or consolidated, or any corporation resulting from
any merger or consolidation to which the Depositor, the Company or the Master
Servicer shall be a party, or any Person succeeding to the business of the
Depositor, the Company or the Master Servicer, shall be the successor of the
Depositor, the Company or 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 8.03      INDEMNIFICATION OF THE TRUSTEE, THE MASTER SERVICER
                           AND THE SECURITIES ADMINISTRATOR.

                  (a) The Master Servicer agrees to indemnify the Indemnified
Persons for, and to hold them harmless against, any loss, liability or expense
(including reasonable legal fees and disbursements of counsel) incurred on their
part that may be sustained in connection with, arising out of, or relating to,
any claim or legal action (including any pending or threatened claim or legal
action) relating to this Agreement, including the powers of attorney delivered
pursuant to Sections 4.01 and 4.05 hereof, the Assignment Agreements, the
Custodial 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; provided, however that the failure to give such notice shall not
relieve the Master Servicer of its indemnification obligations hereunder. This
indemnity shall


                                      -110-

<PAGE>



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

                  (b) The Company agrees to indemnify the Indemnified Persons
and to hold them harmless from and against any and all claims, losses, damages,
penalties, fines, forfeitures, legal fees and related costs, judgments, and any
other costs, fees and expenses that the Indemnified Persons may sustain in any
way related to the failure of the Company to perform in any way its duties and
service the EMC Mortgage Loans in strict compliance with the terms of this
Agreement and for breach of any representation or warranty of the Company
contained herein. The Company shall immediately notify the Master Servicer and
the Trustee if a claim is made by a third party with respect to this Agreement
or the EMC Mortgage Loans, assume (with the consent of the Master Servicer and
the Trustee and with counsel reasonably satisfactory to the Master Servicer and
the Trustee) the defense of any such claim and pay all expenses in connection
therewith, including counsel fees, and promptly pay, discharge and satisfy any
judgment or decree which may be entered against it or any Indemnified Person in
respect of such claim but failure to so notify the Company shall not limit its
obligations hereunder. The Company agrees that it will not enter into any
settlement of any such claim without the consent of the Indemnified Persons
unless such settlement includes an unconditional release of such Indemnified
Persons from all liability that is the subject matter of such claim. The
provisions of this Section 8.03(b) shall survive termination of this Agreement.

                  (c) The Seller will indemnify any Indemnified Person for any
loss, liability or expense of any Indemnified Person not otherwise paid or
covered pursuant to Subsections (a) or (b) above.

         Section 8.04 LIMITATIONS ON LIABILITY OF THE DEPOSITOR, THE COMPANY,
THE MASTER SERVICER AND OTHERS. Subject to the obligation of the Depositor, the
Company and the Master Servicer to indemnify the Indemnified Persons pursuant to
Section 8.03:

                  (a) Neither the Depositor, the Company, the Master Servicer
nor any of the directors, officers, employees or agents of the Depositor, the
Company and the Master Servicer shall be under any liability to the Indemnified
Persons, 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 Depositor, the Company, 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 Depositor, the Company, the Master Servicer and any
director, officer, employee or agent of the Depositor, the Company and 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 Depositor, the Company, the Master Servicer, the
Trustee, the Custodian and any director, officer, employee or agent of the
Depositor, the Company, the Master Servicer, the


                                      -111-

<PAGE>



Trustee 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 Assignment Agreements, the Custodial Agreement, the Certificates
or the Servicing Agreements (except with respect to the Master Servicer only, to
the extent that the Master Servicer is indemnified by the Company under this
Agreement or by the related Servicer under the related Servicing Agreement),
other than (i) any such loss, liability or expense related to the Company's or
the Master Servicer's failure to perform its respective 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, or (ii) any such
loss, liability or expense incurred by reason of the Company's, 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) Neither the Depositor, the Company nor the Master Servicer
shall be under any obligation to appear in, prosecute or defend any legal action
that is not incidental to its duties under this Agreement and that in its
opinion may involve it in any expense or liability; provided, however, the
Master Servicer may in its discretion, with the consent of the Trustee (which
consent shall not be unreasonably withheld), undertake any such action which it
may deem necessary or desirable with respect to this Agreement and the rights
and duties of the parties hereto and the interests of the Certificateholders
hereunder. In such event, the legal expenses and costs of such action and any
liability resulting therefrom shall be expenses, costs and liabilities of the
Trust Fund, and the Master Servicer shall be entitled to be reimbursed therefor
out of the Master Servicer Collection Account as provided by Section 5.05.
Nothing in this Subsection 8.04(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 4.01(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 Company or the Servicers, except as otherwise expressly
provided herein.

         Section 8.05 MASTER SERVICER AND COMPANY NOT TO RESIGN. (a) Except as
provided in Section 8.07, the Master Servicer shall not resign from the
obligations and duties hereby imposed on it except (i) with the prior written
consent of the Trustee (which consent shall not be unreasonably withheld) or
(ii) 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 Counsel to such effect, addressed to and 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


                                      -112-

<PAGE>



the Trustee shall have assumed the responsibilities and obligations of the
Master Servicer in accordance with Section 9.02 hereof. The Trustee shall notify
the Rating Agencies of the resignation of the Master Servicer.

                  (b) The Company shall not resign from the obligations and
duties hereby imposed on it except (i) upon the assignment of its servicing
duties with respect to all or a portion of the EMC Mortgage Loans to an
institution that is a Fannie Mae and Freddie Mac approved seller/servicer in
good standing that has a net worth of not less than $10,000,000 and with the
prior written consent of the Master Servicer (which consent shall not be
unreasonably withheld) or (ii) upon the determination that its duties hereunder
are no longer permissible under applicable law and such incapacity cannot be
cured by the Company. Any determination permitting the resignation of the
Company shall be evidenced by an Opinion of Counsel to such effect addressed to
and delivered, to the Master Servicer and the Trustee which Opinion of Counsel
shall be in form and substance acceptable to the Master Servicer and the
Trustee. No appointment of a successor to the Company shall be effective
hereunder unless (a) the Rating Agencies have confirmed in writing that such
appointment will not result in a downgrade, qualification or withdrawal of the
then current ratings assigned to the Certificates, (b) such successor shall have
represented that it is meets the eligibility criteria set forth in clause (i)
above and (c) such successor has agreed to assume the obligations of the Company
hereunder to the extent of the EMC Mortgage Loans to be serviced by such
successor. The Company shall provide a copy of the written confirmation of the
Rating Agencies and the agreement executed by such successor to the Master
Servicer and the Trustee. No such resignation shall become effective until a
Qualified Successor or the Master Servicer shall have assumed the Company's
responsibilities and obligations hereunder. The Company shall notify the Master
Servicer, the Trustee and the Rating Agencies of the resignation of the Company
or the assignment of all or a portion of its servicing duties hereunder in
accordance with this Section 8.05.

         Section 8.06 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. In no event shall the compensation of any successor master
servicer exceed that permitted the Master Servicer without the consent of all of
the Certificateholders.

         Section 8.07 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

$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

and condition to be performed or observed by it as master servicer under this
Agreement, any custodial agreement from and after the effective date of such
agreement; (ii) each Rating Agency shall be given prior written notice of the
identity of the proposed successor to the Master Servicer and each Rating
Agency's rating of the Certificates in effect immediately prior to such
assignment, sale and delegation will not be downgraded, qualified or withdrawn
as a result of such assignment, sale and delegation, as evidenced by a letter to
such effect delivered to the Master Servicer and the Trustee; (iii) the Master
Servicer assigning and selling the master servicing shall deliver to the Trustee
an Officer's Certificate and an Opinion of Counsel addressed to the Trustee,
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, from its own funds and without any right of
reimbursement, the terminated Master Servicer a termination fee equal to 0.25%
of the aggregate Stated Principal Balance of the Mortgage Loans at the time the
master servicing of the Mortgage Loans is transferred to the successor Master
Servicer. No such assignment or delegation shall affect any liability of the
Master Servicer arising prior to the effective date thereof.

                    DEFAULT; TERMINATION OF MASTER SERVICER;
                             TERMINATION OF COMPANY

         Section 9.01      EVENTS OF DEFAULT.

         "Event of Default," wherever used herein, means any one of the
following events:

                  (i) any failure by the Master Servicer to remit to the Trustee
         any amounts received or collected by the Master Servicer in respect of
         the Mortgage Loans and required to be remitted by it hereunder or any
         Advance required to be made by it pursuant to this Agreement, which
         failure shall continue unremedied for one Business Day after the date
         on which written notice of such failure shall have been given to the
         Master Servicer by the Trustee or the Depositor, or to the Trustee and
         the Master Servicer by the Holders of Certificates evidencing not less
         than 25% of the Voting Rights evidenced by the Certificates; or

                  (ii) any failure by the Master Servicer to observe or perform
         in any material respect any other of the covenants or agreements on the
         part of the Master Servicer contained in this Agreement or any breach
         of a representation or warranty by the Master Servicer, which failure
         or breach shall continue unremedied for a period of 60 days after the
         date on which written notice of such failure shall have been given to
         Master Servicer by the Trustee or the Depositor, or to the Trustee and
         the Master Servicer by the Holders of Certificates evidencing not less
         than 25% of the Voting Rights evidenced by the Certificates; or

                  (iii) a decree or order of a court or agency or supervisory
         authority having jurisdiction in the premises for the appointment of a
         receiver or liquidator in any insolvency, readjustment of debt,
         marshalling of assets and liabilities or similar proceedings, or for
         the winding-up or liquidation of its affairs, shall have been entered
         against the Master Servicer and such decree or order shall have
         remained in force undischarged or unstayed for a period of 60
         consecutive days; or

                  (iv) the Master Servicer shall consent to the appointment of a
         receiver or liquidator in any insolvency, readjustment of debt,
         marshalling of assets and liabilities or similar proceedings of or
         relating to the Master Servicer or all or substantially all of the
         property of the Master Servicer; or

                  (v) the Master Servicer shall admit in writing its inability
         to pay its debts generally as they become due, file a petition to take
         advantage of, or commence a voluntary case under, any applicable
         insolvency or reorganization statute, make an assignment for the
         benefit of its creditors, or voluntarily suspend payment of its
         obligations; or

                  (vi) 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 8.05 or 8.07.

                  If an Event of Default shall occur, then, and in each and
every such case, so long as such Event of Default shall not have been remedied,
the Trustee may, and at the direction of the Holders of Certificates evidencing
not less than 25% of the Voting Rights evidenced by the Certificates, the
Trustee shall, by notice in writing to the Master Servicer (with a copy to each
Rating Agency), terminate all of the rights and obligations of the Master
Servicer (and the Securities Administrator if the Master Servicer and the
Securities Administrator are the same entity) under this Agreement and in and to
the Mortgage Loans and the proceeds thereof, other than its rights as a
Certificateholder hereunder. On or after the receipt by the Master Servicer of
such written notice, all authority and power of the Master Servicer (and, if
applicable, the Securities Administrator) hereunder, whether with respect to the
Mortgage Loans or otherwise, shall pass to and be vested in the Trustee, or any
successor appointed pursuant to Section 9.02 (a "Successor Master Servicer" and,
if applicable, "Successor Securities Administrator"). Such Successor Master
Servicer shall thereupon if such Successor Master Servicer is a successor to the
Master Servicer, make any Advance required by Article VI, subject, in the case
of the Trustee, to Section 9.02. The Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the terminated Master Servicer and, if
applicable, the terminated Securities Administrator, 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 any Mortgage Loans and related documents, or otherwise. Unless
expressly provided in such written notice, no such termination shall affect any
obligation of the Master Servicer to pay amounts owed pursuant to Article VIII
or Article X. The Master Servicer and, if applicable, the Securities
Administrator agrees to cooperate with the Trustee in effecting the termination
of the Master Servicer's and, if applicable, the Securities Administrator's
responsibilities and rights hereunder, including, without limitation, the
transfer to the applicable Successor Master Servicer of all cash amounts which
shall at the time be credited to the Master Servicer Collection Account
maintained pursuant to Section 5.05, or thereafter be received with respect to
the applicable Mortgage Loans. The Trustee shall promptly notify the Rating
Agencies of the occurrence of an Event of Default known to the Trustee.

                  Notwithstanding any termination of the activities of the
Master Servicer hereunder, the Master Servicer shall be entitled to receive, out
of any late collection of a Scheduled Payment on a Mortgage Loan that was due
prior to the notice terminating the Master Servicer's rights and obligations as
Master Servicer hereunder and received after such notice, that portion thereof
to which the Master Servicer would have been entitled pursuant to Sections 5.05
and to receive any other amounts payable to the Master Servicer hereunder the
entitlement to which arose prior to the termination of its activities hereunder.

         Section 9.02      TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

                  On and after the time the Master Servicer receives a notice of
termination pursuant to Section 9.01 hereof the Trustee shall automatically
become the successor to the Master Servicer with respect to the transactions set
forth or provided for herein and after a transition period (not to exceed 90
days), shall be subject to all the responsibilities, duties and liabilities
relating thereto placed on the Master Servicer by the terms and provisions
hereof; provided, however that, pursuant to Article VI hereof, the Trustee in
its capacity as successor Master Servicer shall be responsible for making any
Advances required to be made by the Master Servicer immediately upon the
termination


                                      -116-

<PAGE>



of the Master Servicer and any such Advance shall be made on the Distribution
Date on which such Advance was required to be made by the predecessor Master
Servicer. Effective on the date of such notice of termination, as compensation
therefor, the Trustee shall be entitled to all compensation, reimbursement of
expenses and indemnifications that the Master Servicer would have been entitled
to if it had continued to act hereunder, provided, however, that the Trustee
shall not be (i) liable for any acts or omissions of the Master Servicer, (ii)
obligated to make Advances if it is prohibited from doing so under applicable
law, (iii) responsible for expenses of the Master Servicer pursuant to Section
2.03 or (iv) obligated to deposit losses on any Permitted Investment directed by
the Master Servicer. Notwithstanding the foregoing, the Trustee may, if it shall
be unwilling to so act, or shall, if it is prohibited by applicable law from
making Advances pursuant to Article VI or if it is otherwise unable to so act,
appoint, or petition a court of competent jurisdiction to appoint, any
established mortgage loan servicing institution the appointment of which does
not adversely affect the then current rating of the Certificates by each Rating
Agency 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. Any Successor Master Servicer shall (i) be an institution
that is a Fannie Mae and Freddie Mac approved seller/servicer in good standing,
that has a net worth of at least $15,000,000 and (ii) be willing to act as
successor servicer of any Mortgage Loans under this Agreement or the related
Servicing Agreement with respect to which the Company or the original Servicer
has been terminated as servicer, and shall have executed and delivered to the
Depositor and the Trustee an agreement accepting such delegation and assignment,
that contains an assumption by such Person of the rights, powers, duties,
responsibilities, obligations and liabilities of the Master Servicer (other than
any liabilities of the Master Servicer hereof incurred prior to termination of
the Master Servicer under Section 9.01 or as otherwise set forth herein), with
like effect as if originally named as a party to this Agreement, provided that
each Rating Agency shall have acknowledged in writing that its rating of the
Certificates in effect immediately prior to such assignment and delegation will
not be qualified or reduced as a result of such assignment and delegation. If
the Trustee assumes the duties and responsibilities of the Master Servicer in
accordance with this Section 9.02, the Trustee shall not resign as Master
Servicer until a Successor Master Servicer has been appointed and has accepted
such appointment. Pending appointment of a successor to the Master Servicer
hereunder, the Trustee, unless the Trustee is prohibited by law from so acting,
shall, subject to Section 4.04 hereof, 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
Mortgage Loans or otherwise as it and such successor shall agree; provided that
no such compensation unless agreed to by the Certificateholders shall be in
excess of that permitted the Master Servicer hereunder. The Trustee and such
successor shall take such action, consistent with this Agreement, as shall be
necessary to effectuate any such succession. Neither the Trustee nor any other
Successor Master Servicer shall be deemed to be in default hereunder by reason
of any failure to make, or any delay in making, any distribution hereunder or
any portion thereof or any failure to perform, or any delay in performing, any
duties or responsibilities hereunder, in either case caused by the failure of
the Master Servicer and the Securities Administrator to deliver or provide, or
any delay in delivering or providing, any cash, information, documents or
records to it.

                  The costs and expenses of the Trustee in connection with the
termination of the Master Servicer, appointment of a Successor Master Servicer
and, if applicable, any transfer of servicing, including, without limitation,
all costs and expenses associated with the complete transfer


                                      -117-

<PAGE>



of all servicing data and the completion, correction or manipulation of such
servicing data as may be required by the Trustee to correct any errors or
insufficiencies in the servicing data or otherwise to enable the Trustee or the
Successor Master Servicer to service the related Mortgage Loans properly and
effectively, to the extent not paid by the terminated Master Servicer, shall be
payable to the Trustee pursuant to Section 10.05. Any successor to the Master
Servicer as successor servicer under any Subservicing Agreement shall give
notice to the applicable Mortgagors of such change of servicer and shall, during
the term of its service as successor servicer maintain in force the policy or
policies that the Master Servicer is required to maintain pursuant to Section
4.04.

         Section 9.03      NOTIFICATION TO CERTIFICATEHOLDERS.

                  (a) Upon any termination of or appointment of a successor to
the Master Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders and to each Rating Agency.

                  (b) Within 60 days after the occurrence of any Event of
Default, the Trustee shall transmit by mail to all Certificateholders notice of
each such Event of Default hereunder actually known to a Responsible Officer of
the Trustee, unless such Event of Default shall have been cured or waived.

         Section 9.04      WAIVER OF DEFAULTS.

                  The Trustee shall transmit by mail to all Certificateholders,
within 60 days after the occurrence of any Event of Default actually known to a
Responsible Officer of the Trustee, unless such Event of Default shall have been
cured, notice of each such Event of Default hereunder known to the Trustee. The
Holders of Certificates evidencing not less than 51% of the Voting Rights 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 of 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 9.05      COMPANY DEFAULT.

                  In case one or more of the following events of default by the
Company (each, a "Company Default") shall occur and be continuing, that is to
say:

                  (i) any failure by the Company to remit to the Master Servicer
any payment required to be made under the terms of this Agreement on any
Remittance Date; or

                  (ii) failure on the part of the Company duly to observe or
perform in any material respect any other of the covenants or agreements on the
part of the Company set forth in this Agreement, the breach of which has a
material adverse effect and which continue unremedied for a period of sixty days
(except that such number of days shall be fifteen in the case of a failure to
pay any premium for any insurance policy required to be maintained under this
Agreement and such


                                      -118-

<PAGE>



failure shall be deemed to have a material adverse effect) after the date on
which written notice of such failure, requiring the same to be remedied, shall
have been given to the Company by the Master Servicer; or

                  (iii) a decree or order of a court or agency or supervisory
authority having jurisdiction for the appointment of a conservator or receiver
or liquidator in any insolvency, bankruptcy, readjustment of debt, marshaling of
assets and liabilities or similar proceedings, or for the winding-up or
liquidation of its affairs, shall have been entered against the Company and such
decree or order shall have remained in force undischarged or unstayed for a
period of sixty days; or

                  (iv) the Company shall consent to the appointment of a
conservator or receiver or liquidator in any insolvency, bankruptcy,
readjustment of debt, marshaling of assets and liabilities or similar
proceedings of or relating to the Company or of or relating to all or
substantially all of its property; or

                  (v) the Company shall admit in writing its inability to pay
its debts generally as they become due, file a petition to take advantage of any
applicable insolvency or reorganization statute, make an assignment for the
benefit of its creditors, or voluntarily suspend payment of its obligations; or

                  (vi) the Company attempts to assign its right to servicing
compensation hereunder or the Company attempts to sell or otherwise dispose of
all or substantially all of its property or assets or to assign this Agreement
or the servicing responsibilities hereunder or to delegate its duties hereunder
or any portion thereof except as otherwise permitted herein; or

                  (vii) the Company ceases to be qualified to transact business
in any jurisdiction where it is currently so qualified, but only to the extent
such non-qualification materially and adversely affects the Company's ability to
perform its obligations hereunder;

         then, and in each and every such case, so long as a Company Default
shall not have been remedied, the Master Servicer, by notice in writing to the
Company may, in addition to whatever rights the Master Servicer and the Trustee
on behalf of the Certificateholders may have under Section 8.03 and at law or
equity to damages, including injunctive relief and specific performance,
terminate all the rights and obligations of the Company under this Agreement and
in and to the EMC Mortgage Loans and the proceeds thereof without compensating
the Company for the same. On or after the receipt by the Company of such written
notice, all authority and power of Company under this Agreement, whether with
respect to the EMC Mortgage Loans or otherwise, shall pass to and be vested in
the Master Servicer. Upon written request from the Master Servicer, the Company
shall prepare, execute and deliver, any and all documents and other instruments,
place in the Master Servicer's possession all Mortgage Files relating to the EMC
Mortgage Loans, and 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 EMC Mortgage Loans
and related documents, or otherwise, at the Company's sole expense. The Company
agrees to cooperate with the Master Servicer in effecting the termination of the
Company's responsibilities and rights hereunder, including, without limitation,
the transfer to such successor for administration by it of all cash amounts
which shall at the time be credited by the Company to its Protected Account or
Escrow


                                      -119-

<PAGE>



Account or thereafter received with respect to the EMC Mortgage Loans or any
related REO Property.

         Section 9.06      WAIVER OF COMPANY DEFAULTS.

         The Master Servicer, with the consent of the Trustee, may waive only by
written notice any default by the Company in the performance of its obligations
hereunder and its consequences. Upon any such waiver of a past default, such
default shall cease to exist, and any Company Default arising therefrom shall be
deemed to have been 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 in writing.

             CONCERNING THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

         Section 10.01     DUTIES OF TRUSTEE AND SECURITIES ADMINISTRATOR.

                  (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 the same degree
         of care and skill in their exercise, as a prudent person would exercise
         under the circumstances in the conduct of such Person's 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 or the Securities
         Administrator pursuant to any provision of this Agreement, the Trustee
         or the Securities Administrator, respectively, shall examine them to
         determine whether they are, on their face, 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 6.04 and
         11.01 herein based solely on the applicable Remittance Report.

                  (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 with respect to the Trustee and at all times with respect to
         the Securities Administrator, 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


                                      -121-

<PAGE>



         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 Responsible Officers of
         the Trustee or an officer or officers 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 not less than 25% of the
         aggregate Voting Rights of the Certificates, 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 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 in a
         non-appealable judgment that the Trustee's gross negligence or willful
         misconduct was the primary cause of such insufficiency (except to the
         extent that the Trustee is obligor and has defaulted thereon);

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

                  (vii) None of the Securities Administrator, the Master
         Servicer, the Seller, the Depositor 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


                                      -122-

obligations of the Master Servicer or the Company hereunder or any Servicer
under the related Servicing Agreement.

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

       Section 10.02 CERTAIN MATTERS AFFECTING THE TRUSTEE AND THE SECURITIES
                     ADMINISTRATOR.

                  (a) Except as otherwise provided in Section 10.01:

                  (i) The Trustee and the Securities Administrator may rely and
         shall be protected in acting or refraining from acting in reliance on
         any resolution or certificate of the Seller, the Company, the Master
         Servicer or the related Servicer, any certificates 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 or the Securities Administrator, as applicable, reasonable
         security or indemnity against the costs, expenses and liabilities which
         may be incurred therein or thereby. Nothing contained herein shall,
         however, relieve the Trustee of the obligation, upon the occurrence of
         an Event of Default of which a Responsible Officer of the Trustee has
         actual knowledge (which has not been cured or waived), 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 with respect to the Trustee and at all times with respect to
         the Securities Administrator, 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


                                      -123-

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

                  (vi) The Trustee and the Securities Administrator may execute
         any of the trusts or powers hereunder or perform any duties hereunder
         either directly or through Affiliates, agents or attorneys; provided,
         however, that the Trustee may not appoint any paying agent other than
         the Securities Administrator to perform any 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 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 to be unclear, the
         Trustee or the Securities Administrator, respectively, may require
         prior to such action that it be provided by the Depositor with
         reasonable further instructions; 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;

                  (viii) 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 10.07; and

                  (ix) 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 any Person pursuant to this Agreement, or the eligibility of
         any Mortgage Loan for purposes of this Agreement.

         Section 10.03 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 Depositor, 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


                                      -124-

<PAGE>



validity or sufficiency of the Certificates (other than the signature and
countersignature of the Trustee on the Certificates) or of any Mortgage Loan
except as expressly provided in Sections 2.02 and 2.06 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 2.05 of this Agreement.
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 Depositor of any of the Certificates or of the
proceeds of such Certificates, or for the use or application of any funds paid
to the Depositor with respect to the Mortgage Loans. Subject to the provisions
of Section 2.06, neither the Trustee nor the Securities Administrator shall be
responsible for the legality or validity of this Agreement or any document or
instrument relating to this Agreement, the validity of the execution of this
Agreement or of any supplement hereto or instrument of further assurance, or the
validity, priority, perfection or sufficiency of the security for the
Certificates issued hereunder or intended to be issued hereunder. Neither the
Trustee nor the Securities Administrator shall at any time have any
responsibility or liability for or with respect to the legality, validity and
enforceability of any Mortgage or any Mortgage Loan, or the perfection and
priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with respect to the sufficiency of the Trust Fund or its ability to
generate the payments to be distributed to Certificateholders, under this
Agreement. Neither the Trustee nor the Securities Administrator shall have any
responsibility for filing any financing or continuation statement in any public
office at any time or to otherwise perfect or maintain the perfection of any
security interest or lien granted to it hereunder or to record this Agreement.

        Section 10.04 TRUSTEE AND SECURITIES ADMINISTRATOR MAY OWN
                      CERTIFICATES.

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

        Section 10.05 TRUSTEE'S AND SECURITIES ADMINISTRATOR'S FEES AND
                      EXPENSES.

                  The fees and expenses of the Trustee and the Securities
Administrator shall be paid in accordance with a side letter agreement with the
Master Servicer and at the expense of the Master Servicer. In addition, the
Trustee and the Securities Administrator will be entitled to recover from the
Master Servicer Collection Account pursuant to Section 5.06 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 Master Servicer Collection Account are insufficient therefor, the Trustee
and the Securities Administrator shall recover such expenses from the Depositor.
Such compensation and


                                      -125-

<PAGE>



reimbursement obligation shall not be limited by any provision of law in regard
to the compensation of a trustee of an express trust.

         Section 10.06 ELIGIBILITY REQUIREMENTS FOR TRUSTEE AND SECURITIES
                       ADMINISTRATOR.

                  The Trustee and any successor Trustee and the Securities
Administrator and any successor Securities Administrator shall during the entire
duration of this Agreement be a state bank or trust company or a national
banking association organized and doing business under the laws of a state or
the United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus and undivided profits of at
least $40,000,000 or, in the case of a successor Trustee, $50,000,000, subject
to supervision or examination by federal or state authority and, in the case of
the Trustee, rated "BBB" or higher by Fitch with respect to their long-term
rating and rated "BBB" or higher by Standard & Poor's and "Baa2" or higher by
Moody's with respect to any outstanding long-term unsecured unsubordinated debt,
and, in the case of a successor Trustee or successor Securities Administrator
other than pursuant to Section 10.10, rated in one of the two highest long-term
debt categories of, or otherwise acceptable to, each of the Rating Agencies. The
Trustee shall not be an Affiliate of the Master Servicer. 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 10.06 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, as applicable,
shall cease to be eligible in accordance with the provisions of this Section
10.06, the Trustee or the Securities Administrator shall resign immediately in
the manner and with the effect specified in Section 10.08.

         Section 10.07     INSURANCE.

                  The Trustee and the Securities Administrator, at their own
expense, shall at all times maintain and keep in full force and effect: (i)
fidelity insurance, (ii) theft of documents insurance and (iii) forgery
insurance (which may be collectively satisfied by a "Financial Institution Bond"
and/or a "Bankers' Blanket Bond"). All such insurance shall be in amounts, with
standard coverage and subject to deductibles, as are customary for insurance
typically maintained by banks or their affiliates which act as custodians for
investor-owned mortgage pools. A certificate of an officer of the Trustee or the
Securities Administrator as to the Trustee's or the Securities Administrator's,
respectively, compliance with this Section 10.07 shall be furnished to any
Certificateholder upon reasonable written request.

        Section 10.08 RESIGNATION AND REMOVAL OF TRUSTEE AND SECURITIES
                      ADMINISTRATOR.

                  The Trustee and the Securities Administrator may at any time
resign (including, in the case of the Securities Administrator, in connection
with the resignation or termination of the Master Servicer) and be discharged
from the Trust hereby created by giving written notice thereof to the Depositor,
the Seller, the Securities Administrator (or the Trustee, if the Securities
Administrator resigns) and the Master Servicer, with a copy to the Rating
Agencies. Upon receiving such notice of resignation, the Depositor shall
promptly appoint a successor trustee or successor securities administrator, as
applicable, by written instrument, in triplicate, one copy of which


                                      -126-

<PAGE>



instrument shall be delivered to each of the resigning trustee or securities
administrator, as applicable, and the successor trustee or securities
administrator, as applicable. If no successor trustee or successor 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.

                  If at any time (i) the Trustee or the Securities Administrator
shall cease to be eligible in accordance with the provisions of Section 10.06
hereof and shall fail to resign after written request thereto by the Depositor,
(ii) the Trustee or the Securities Administrator shall become incapable of
acting, or shall be adjudged as bankrupt or insolvent, or a receiver of the
Trustee or the Securities Administrator or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or the
Securities Administrator or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, or (iii)(A) a tax is imposed with
respect to the Trust Fund by any state in which the Trustee or the Securities
Administrator or the Trust Fund is located, (B) the imposition of such tax would
be avoided by the appointment of a different trustee or securities administrator
and (C) the Trustee or the Securities Administrator, as applicable fails to
indemnify the Trust Fund against such tax, then the Depositor or the Master
Servicer may remove the Trustee or the Securities Administrator, as applicable,
and appoint a successor trustee or successor securities administrator, as
applicable, by written instrument, in multiple copies, a copy of which
instrument shall be delivered to the Trustee, the Securities Administrator, each
Master Servicer and the successor trustee or successor securities administrator,
as applicable.

                  The Holders evidencing at least 51% of the Voting Rights of
each Class of Certificates may at any time remove the Trustee or Securities
Administrator and appoint a successor trustee or securities administrator by
written instrument or instruments, in multiple copies, signed by such Holders or
their attorneys-in-fact duly authorized, one complete set of which instruments
shall be delivered by the successor trustee or successor securities
administrator to each of the Master Servicer, the Trustee or Securities
Administrator so removed and the successor trustee or securities administrator
so appointed. Notice of any removal of the Trustee or Securities Administrator
shall be given to each Rating Agency by the Trustee or successor trustee.

                  Any resignation or removal of the Trustee or Securities
Administrator and appointment of a successor trustee or securities administrator
pursuant to any of the provisions of this Section 10.08 shall become effective
upon acceptance of appointment by the successor trustee or securities
administrator as provided in Section 10.09 hereof.

         Section 10.09     SUCCESSOR TRUSTEE OR SECURITIES ADMINISTRATOR.

                  Any successor trustee or securities administrator appointed as
provided in Section 10.08 hereof shall execute, acknowledge and deliver to the
Depositor and to its predecessor trustee or predecessor securities
administrator, as applicable, and the Master Servicer an instrument accepting
such appointment hereunder and thereupon the resignation or removal of the
predecessor trustee or securities administrator shall become effective and such
successor trustee or securities administrator, without any further act, deed or
conveyance, shall become fully vested with all the


                                      -127-

<PAGE>



rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as trustee or securities administrator
herein.

                  No successor trustee or securities administrator shall accept
appointment as provided in this Section 10.09 unless at the time of such
acceptance such successor trustee or securities administrator shall be eligible
under the provisions of Section 10.07 hereof and its appointment shall not
adversely affect the then current rating of the Certificates.

                  Upon acceptance of appointment by a successor trustee or
securities administrator as provided in this Section 10.09, the successor
trustee or securities administrator shall mail notice of the succession of such
trustee or securities administrator hereunder to all Holders of Certificates. If
the successor trustee or securities administrator fails to mail such notice
within ten days after acceptance of appointment, the Depositor shall cause such
notice to be mailed at the expense of the Trust Fund.

         Section 10.10     MERGER OR CONSOLIDATION OF TRUSTEE OR SECURITIES
                           ADMINISTRATOR.

                  Any corporation, state bank 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 corporation, state bank or
national banking association resulting from any merger, conversion or
consolidation to which the Trustee or the Securities Administrator shall be a
party, or any corporation, state bank or national banking association succeeding
to substantially all of the corporate trust business of the Trustee or of the
business of the Securities Administrator, shall be the successor of the Trustee
or the Securities Administrator hereunder, provided that such corporation shall
be eligible under the provisions of Section 10.06 hereof 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 10.11     APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.

                  Notwithstanding any other provisions of this Agreement, at any
time, for the purpose of meeting any legal requirements of any jurisdiction in
which any part of the Trust Fund or property securing any Mortgage Note may at
the time be located, the Master Servicer 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 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 Fund, and to vest in such Person or Persons, in such capacity and
for the benefit of the Certificateholders, such title to the Trust Fund or any
part thereof, whichever is applicable, and, subject to the other provisions of
this Section 10.11, such powers, duties, obligations, rights and trusts as the
Master Servicer and the Trustee may consider necessary or desirable. If the
Master Servicer shall not have joined in such appointment within 15 days after
the receipt by it of a request to do so, or in the case an Event of Default
shall have occurred and be continuing, the Trustee alone shall have the power to
make such appointment. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
10.06 and no notice to Certificateholders of the appointment of any co-trustee
or separate trustee shall be required under Section 10.09.



                                      -128-

<PAGE>



                  Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                  (i) All rights, powers, duties and obligations conferred or
         imposed upon the Trustee, except for the obligation of the Trustee
         under this Agreement to advance funds on behalf of the Master Servicer,
         shall be conferred or imposed upon and exercised or performed by the
         Trustee and such separate trustee or co-trustee jointly (it being
         understood that such separate trustee or co-trustee is not authorized
         to act separately without the Trustee joining in such act), except to
         the extent that under any law of any jurisdiction in which any
         particular act or acts are to be performed (whether a Trustee hereunder
         or as a Successor 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 Fund or any portion thereof in any such
         jurisdiction) shall be exercised and performed singly by such separate
         trustee or co-trustee, but solely at the direction of the Trustee;

                  (ii) No trustee hereunder shall be held personally liable by
         reason of any act or omission of any other trustee hereunder; and

                  (iii) The Trustee may at any time accept the resignation of or
         remove any separate trustee or co-trustee.

                  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 X. Each separate trustee and co-trustee, upon its
acceptance of the trusts conferred, shall be vested with the estates or property
specified in its instrument of appointment, either jointly with the Trustee or
separately, as may be provided therein, subject to all the provisions of this
Agreement, specifically including every provision of this Agreement relating to
the conduct of, affecting the liability of, or affording protection to, the
Trustee. Every such instrument shall be filed with the Trustee and a copy
thereof given to the Master Servicer and the Depositor.

                  Any separate trustee or co-trustee may, at any time,
constitute the Trustee its agent or attorney-in-fact, with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of 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.

         Section 10.12     TAX MATTERS.

                  It is intended that the Trust Fund shall constitute, and that
the affairs of the Trust Fund shall be conducted so that each REMIC formed
hereunder qualifies as, a "real estate mortgage investment conduit" as defined
in and in accordance with the REMIC Provisions. In furtherance of such
intention, the Securities Administrator covenants and agrees that it shall act
as agent for so long as it is also Master Servicer (and the Securities
Administrator is hereby appointed to act as agent)


                                      -129-

<PAGE>



on behalf of the Trust Fund. The Trustee and/or the Securities Administrator, as
agent on behalf of the Trust Fund, shall do or refrain from doing, as
applicable, the following: (a) the Securities Administrator shall prepare and
file, or cause to be prepared and filed, in a timely manner, U.S. Real Estate
Mortgage Investment Conduit Income Tax Returns (Form 1066 or any successor form
adopted by the Internal Revenue Service) and prepare and file or cause to be
prepared and filed with the Internal Revenue Service and applicable state or
local tax authorities income tax or information returns for each taxable year
with respect to each such REMIC containing such information and at the times and
in the manner as may be required by the Code or state or local tax laws,
regulations, or rules, and furnish or cause to be furnished to
Certificateholders the schedules, statements or information at such times and in
such manner as may be required thereby; (b) the Securities Administrator shall
apply for an employer identification number with the Internal Revenue Service
via a Form SS-4 or other comparable method for each REMIC that is or becomes a
taxable entity, and within thirty days of the Closing Date, furnish or cause to
be furnished to the Internal Revenue Service, on Forms 8811 or as otherwise may
be required by the Code, the name, title, address, and telephone number of the
person that the holders of the Certificates may contact for tax information
relating thereto, together with such additional information as may be required
by such Form, and update such information at the time or times in the manner
required by the Code for the Trust Fund; (c) the Trustee shall make or cause to
be made elections, on behalf of each REMIC formed hereunder to be treated as a
REMIC on the federal tax return of such REMIC for its first taxable year (and,
if necessary, under applicable state law); (d) the Securities Administrator
shall prepare and forward, or cause to be prepared and forwarded, to the
Certificateholders and to the Internal Revenue Service and, if necessary, state
tax authorities, all information returns and reports as and when required to be
provided to them in accordance with the REMIC Provisions, including without
limitation, the calculation of any original issue discount using the Prepayment
Assumption; (e) the Securities Administrator shall provide information necessary
for the computation of tax imposed on the transfer of a Residual Certificate to
a Person that is not a Permitted Transferee, or an agent (including a broker,
nominee or other middleman) of a Person that is not a Permitted Transferee, or a
pass- through entity in which a Person that is not a Permitted Transferee is the
record holder of an interest (the reasonable cost of computing and furnishing
such information may be charged to the Person liable for such tax); (f) each of
the Securities Administrator and the Trustee shall, to the extent under its
control, conduct the affairs of the Trust Fund at all times that any
Certificates are outstanding so as to maintain the status of each REMIC formed
hereunder as a REMIC under the REMIC Provisions; (g) neither the Trustee nor the
Securities Administrator shall knowingly or intentionally take any action or
omit to take any action that would cause the termination of the REMIC status of
any REMIC formed hereunder; (h) the Trustee shall pay, from the sources
specified in the penultimate paragraph of this Section 10.12, as directed by the
Securities Administrator in its Remittance Report, the amount of any federal,
state and local taxes, including prohibited transaction taxes as described
below, imposed on any REMIC formed hereunder prior to the termination of the
Trust Fund when and as the same shall be due and payable (but such obligation
shall not prevent the Trustee, the Securities Administrator at the written
request of the Trustee, or any other appropriate Person from contesting any such
tax in appropriate proceedings and shall not prevent the Securities
Administrator from withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings); (i) the Trustee shall sign or cause to be
signed federal, state or local income tax or information returns or any other
document prepared by the Securities Administrator pursuant to this Section 10.12
requiring a signature thereon by the Trustee; (j) the Securities Administrator
shall maintain records relating to each REMIC formed hereunder including but not
limited to the income,


                                      -130-

expenses, assets and liabilities of each such REMIC and adjusted basis of the
Trust Fund property determined at such intervals as may be required by the Code,
as may be necessary to prepare the foregoing returns, schedules, statements or
information; (k) the Securities Administrator shall, for federal income tax
purposes, maintain books and records with respect to the REMICs on a calendar
year and on an accrual basis; (l) neither the Trustee nor the Master Servicer
shall enter into any arrangement not otherwise provided for in this Agreement by
which the REMICs will receive a fee or other compensation for services nor
permit the REMICs to receive any income from assets other than "qualified
mortgages" as defined in Section 860G(a)(3) of the Code or "permitted
investments" as defined in Section 860G(a)(5) of the Code; and (m) as and when
necessary and appropriate, the Trustee, or at the written request of the
Trustee, the Securities Administrator, shall represent the Trust Fund in any
administrative or judicial proceedings relating to an examination or audit by
any governmental taxing authority, request an administrative adjustment as to
any taxable year of any REMIC formed hereunder, enter into settlement agreements
with any governmental taxing agency, extend any statute of limitations relating
to any tax item of the Trust Fund, and otherwise act on behalf of each REMIC
formed hereunder in relation to any tax matter involving any such REMIC.

                  In order to enable each of the Trustee and the Securities
Administrator to perform its duties as set forth herein, the Depositor shall
provide, or cause to be provided, to the Trustee or the Securities Administrator
within 10 days after the Closing Date all information or data that the Trustee
or the Securities Administrator requests in writing and determines to be
relevant for tax purposes to the valuations and offering prices of the
Certificates, including, without limitation, the price, yield, prepayment
assumption and projected cash flows of the Certificates and the Mortgage Loans.
Thereafter, the Depositor shall provide to the Trustee or the Securities
Administrator promptly upon written request therefor, any such additional
information or data that the Trustee or the Securities Administrator may, from
time to time, request in order to enable the Trustee or the Securities
Administrator to perform its duties as set forth herein. The Depositor hereby
indemnifies each of Trustee and the Securities Administrator for any losses,
liabilities, damages, claims or expenses of the Trustee or the Securities
Administrator arising from any errors or miscalculations of the Trustee or the
Securities Administrator, as applicable, that result from any failure of the
Depositor to provide, or to cause to be provided, accurate information or data
to the Trustee or the Securities Administrator, as applicable, on a timely
basis.

                  In the event that any tax is imposed on "prohibited
transactions" of any of REMIC I, REMIC II or REMIC III as defined in Section
860F(a)(2) of the Code, on the "net income from foreclosure property" of the
Trust Fund as defined in Section 860G(c) of the Code, on any contribution to any
of REMIC I, REMIC II or REMIC III after the startup day pursuant to Section
860G(d) of the Code, or any other tax is imposed, including, without limitation,
any federal, state or local tax or minimum tax imposed upon any of REMIC I,
REMIC II or REMIC III, and is not paid as otherwise provided for herein, such
tax shall be paid by (i) the Trustee or the Securities Administrator, if any
such other tax arises out of or results from a breach by the Trustee or the
Securities Administrator, respectively, of any of its obligations under this
Agreement, (ii) any party hereto (other than the Trustee or the Securities
Administrator) to the extent any such other tax arises out of or results from a
breach by such other party of any of its obligations under this Agreement or
(iii) in all other cases, or in the event that any liable party hereto fails to
honor its obligations under the preceding clauses (i) or (ii), any such tax will
be paid first with amounts otherwise to be distributed to the Class R
Certificateholders, and second with amounts otherwise to be distributed


                                      -131-

<PAGE>



to all other Certificateholders in the following order of priority: first, to
the Class BA Certificates and Class BB Certificates, on a pro rata basis based
on the amounts to be distributed, second, to the Class M-2 Certificates, third,
to the Class M-1 Certificates and fourth to the Class A Certificates and Class
A-IO Certificates (pro rata based on the amounts to be distributed).
Notwithstanding anything to the contrary contained herein, to the extent that
such tax is payable by the Holder of any Certificates, the Trustee is hereby
authorized to retain on any Distribution Date, from the Holders of the Class R
Certificates (and, if necessary, second, from the Holders of the other
Certificates in the priority specified in the preceding sentence), funds
otherwise distributable to such Holders in an amount sufficient to pay such tax.
Following written notification to the Securities Administrator by the Trustee of
any amount payable out of distributions to the Certificateholders pursuant to
the preceding two sentences, the Securities Administrator shall include in its
Remittance Report instructions as to distributions to such parties taking into
account the priorities described in the second preceding sentence. The
Securities Administrator, on written request by the Trustee, agrees to promptly
notify in writing the party liable for any such tax of the amount thereof and
the due date for the payment thereof.

                  The Trustee and the Securities Administrator each agree that,
in the event it should obtain any information necessary for the other party to
perform its obligations pursuant to this Section 10.12, it will promptly notify
and provide such information to such other party. Notwithstanding anything in
this Agreement to the contrary, the Trustee agrees that, in the event that the
Trustee obtains actual knowledge that the Securities Administrator has breached
any of its obligations pursuant to this Section 10.12, the Trustee shall perform
such obligations on its behalf to the extent that the Trustee possesses all
documents necessary to so perform and receives reasonable compensation therefor,
provided, however, that the Trustee shall not be liable for any losses resulting
from any such breach.

         Section 11.01     TERMINATION UPON LIQUIDATION OR REPURCHASE OF ALL
                           MORTGAGE LOANS.

                  Subject to Section 11.03, the obligations and responsibilities
of the Depositor, the Master Servicer, the Securities Administrator, the Seller
and the Trustee created hereby with respect to the Trust Fund shall terminate

Property), (ii) accrued interest thereon at the applicable Mortgage Rate to, but
not including, the first day of the month of such purchase, (iii) the appraised
value of any REO Property in the Trust Fund (up to the Stated Principal Balance
of the related Mortgage Loan), such appraisal to be conducted by an appraiser
mutually agreed upon by the Master Servicer and the Trustee and (iv)
unreimbursed out-of pocket costs of the Company, the Servicers or the Master
Servicer, including unreimbursed servicing advances and the principal portion of
any unreimbursed Advances, made on the Mortgage Loans prior to the exercise of
such repurchase right and (v) any unreimbursed costs and expenses of the Trustee
and the Securities Administrator payable pursuant to Section 10.05 and (b) the
later of (i) the maturity or other liquidation (or any Advance with respect
thereto) of the last Mortgage Loan remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to Certificateholders
of all amounts required to be distributed to them pursuant to this Agreement, as

the descendants of Joseph P. Kennedy, the late Ambassador of the United States
to the Court of St. James, living on the date hereof and (ii) the Latest
Possible Maturity Date.

                  The right to repurchase all Mortgage Loans and REO Properties
pursuant to clause (a) in the preceding paragraph shall be exercisable on or
after the earlier of (i) the 20% Clean-Up Call Date and (ii) the Distribution
Date in August 2013.

         Section 11.02     FINAL DISTRIBUTION ON THE CERTIFICATES.

                  If on any Determination Date, (i) the Master Servicer
determines that there are no Outstanding Mortgage Loans and no other funds or
assets in the Trust Fund other than the funds in the Master Servicer Collection
Account, the Master Servicer shall direct the Securities Administrator to send a
final distribution notice promptly to each Certificateholder or (ii) the
Securities Administrator determines that a Class of Certificates shall be
retired after a final distribution on such Class, the Securities Administrator
shall notify the Certificateholders within five (5) Business Days after such
Determination Date that the final distribution in retirement of such Class of
Certificates is scheduled to be made on the immediately following Distribution
Date. Any final distribution made pursuant to the immediately preceding sentence
will be made only upon presentation and surrender of the related Certificates at
the office of the Trustee specified in the final distribution notice to
Certificateholders. If the Class C Certificateholder elects to terminate the
Trust Fund pursuant to


                                      -133-

<PAGE>



Section 11.01, at least 20 days prior to the date notice is to be mailed to the
Certificateholders, the Majority Class C Certificateholder shall notify the
Depositor, the Securities Administrator, the Trustee of the date the Majority
Class C Certificateholder intends to terminate the Trust Fund. The Master
Servicer shall remit the Mortgage Loan Purchase Price to the Trustee on the
Business Day prior to the Distribution Date for such Optional Termination by the
Majority Class C Certificateholder.

                  Notice of any termination of the Trust Fund, specifying the
Distribution Date on which Certificateholders may surrender their Certificates
for payment of the final distribution and cancellation, shall be given promptly
by the Securities Administrator by letter to Certificateholders mailed not
earlier than the 10th day and no later than the 15th day of the month
immediately preceding the month of such final distribution. Any such notice
shall specify (a) the Distribution Date upon which final distribution on the
Certificates will be made upon presentation and surrender of Certificates at the
office therein designated, (b) the amount of such final distribution, (c) the
location of the office or agency at which such presentation and surrender must
be made and (d) that the Record Date otherwise applicable to such Distribution
Date is not applicable, distributions being made only upon presentation and
surrender of the Certificates at the office therein specified. The Securities
Administrator will give such notice to each Rating Agency at the time such
notice is given to Certificateholders.

                  In the event such notice is given, the Master Servicer shall
cause all funds in the Master Servicer Collection Account to be remitted to the
Trustee for deposit in the Distribution Account on the Business Day prior to the
applicable Distribution Date in an amount equal to the final distribution in
respect of the Certificates. Upon such final deposit with respect to the Trust
Fund and the receipt by the Trustee of a Request for Release therefor, the
Trustee or the Custodian shall promptly release to the Master Servicer, as
applicable the Mortgage Files for the Mortgage Loans and the Trustee shall
execute and deliver any documents prepared and delivered to it which are
necessary to transfer any REO Property.

                  Upon presentation and surrender of the Certificates, the
Trustee shall cause to be distributed to Certificateholders of each Class in
accordance with the Remittance Report the amounts allocable to such Certificates
held in the Distribution Account in the order and priority set forth in Section
6.04 hereof on the final Distribution Date and in proportion to their respective
Percentage Interests.

                  In the event that any affected Certificateholders shall not
surrender Certificates for cancellation within six months after the date
specified in the above mentioned written notice, the Securities Administrator
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 all the
applicable Certificates shall not have been surrendered for cancellation, the
Securities Administrator may take appropriate steps, or may appoint an 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 that remain a part of the Trust Fund. If within one year
after the second notice all Certificates shall not have been surrendered for
cancellation, the Class R Certificateholders shall be entitled to all unclaimed
funds and other assets of the Trust Fund that remain subject hereto.

         Section 11.03     ADDITIONAL TERMINATION REQUIREMENTS.

                  (a) Upon exercise by the Majority Class C Certificateholder of
its purchase option as provided in Section 11.01, the Trust Fund shall be
terminated in accordance with the following additional requirements, unless each
of the Trustee and the Securities Administrator have been supplied with an
Opinion of Counsel addressed to the Trustee, at the expense of the Majority
Class C Certificateholder, to the effect that the failure of the Trust Fund to
comply with the requirements of this Section 11.03 will not (i) result in the
imposition of taxes on "prohibited transactions" of a REMIC, or (ii) cause a
REMIC to fail to qualify as a REMIC at any time that any Certificates are
outstanding:

                  (1) The Majority Class C Certificateholder shall establish a
90-day liquidation period and notify the Trustee and Securities Administrator
thereof, and the Securities Administrator shall in turn specify the first day of
such period in a statement attached to the tax return for each of REMIC I, REMIC
II and REMIC III pursuant to Treasury Regulation Section 1.860F-1. The Majority
Class C Certificateholder shall satisfy all the requirements of a qualified
liquidation under Section 860F of the Code and any regulations thereunder, as
evidenced by an Opinion of Counsel addressed to the Trustee obtained at the
expense of the Majority Class C Certificateholder;

                  (2) During such 90-day liquidation period, and at or prior to
the time of making the final payment on the Certificates, the Securities
Administrator as agent of the Trustee shall sell all of the assets of REMIC I,
REMIC II and REMIC III for cash; and

                  (3) At the time of the making of the final payment on the
Certificates, the Securities Administrator as agent for the Trustee shall
distribute or credit, or cause to be distributed or credited, to the Holders of
the Residual Certificates all cash on hand (other than cash retained to meet
claims), and REMIC I shall terminate at that time.

                  (b) By their acceptance of the Certificates, the Holders
thereof hereby authorize the adoption of a 90-day liquidation period for REMIC
I, REMIC II and REMIC III, which authorization shall be binding upon all
successor Certificateholders.

                  (c) The Securities Administrator as agent for each REMIC
hereby agrees to adopt and sign such a plan of complete liquidation upon the
written request of the Majority Class C Certificateholder, and the receipt of
the Opinion of Counsel referred to in Section 11.03(a)(1) and to take such other
action in connection therewith as may be reasonably requested by the Majority
Class C Certificateholder.

                            MISCELLANEOUS PROVISIONS

         Section 12.01     AMENDMENT.

                  This Agreement may be amended from time to time by parties
hereto, without the consent of any of the Certificateholders to cure any
ambiguity, to correct or supplement any provisions herein (including to give
effect to the expectations of investors), to change the manner in which the
Master Servicer Collection Account maintained by the Master Servicer or the
Protected Account maintained by the Company is maintained or to make such other
provisions with respect to matters or questions arising under this Agreement as
shall not be inconsistent with any other provisions herein if such action shall
not, as evidenced by an Opinion of Counsel addressed to the Trustee, adversely
affect in any material respect the interests of any Certificateholder; provided
that any such amendment shall be deemed not to adversely affect in any material
respect the interests of the Certificateholders and no such Opinion of Counsel
shall be required if the Person requesting such amendment obtains a letter from
each Rating Agency stating that such amendment would not result in the
downgrading or withdrawal of the respective ratings then assigned to the
Certificates.

                  Notwithstanding the foregoing, without the consent of the
Certificateholders, the parties hereto may at any time and from time to time
amend this Agreement to modify, eliminate or add to any of its provisions to
such extent as shall be necessary or appropriate to maintain the qualification
of each of REMIC I, REMIC II and REMIC III as a REMIC under the Code or to avoid
or minimize the risk of the imposition of any tax on any of REMIC I, REMIC II or
REMIC III pursuant to the Code that would be a claim against any of REMIC I,
REMIC II or REMIC III at any time prior to the final redemption of the
Certificates, provided that the Trustee has been provided an Opinion of Counsel
addressed to the Trustee, which opinion shall be an expense of the party
requesting such opinion but in any case shall not be an expense of the Trustee,
the Securities Administrator or the Trust Fund, to the effect that such action
is necessary or appropriate to maintain such qualification or to avoid or
minimize the risk of the imposition of such a tax.

                  This Agreement may also be amended from time to time by the
parties hereto and the Holders of each Class of Certificates affected thereby
evidencing over 50% of the Voting Rights of 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 Holders of Certificates; provided that no such amendment shall (i) reduce in
any manner the amount of, or delay the timing of, payments required to be
distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) cause any of REMIC I, REMIC II or REMIC III to cease to
qualify as a REMIC or (iii) reduce the aforesaid percentages of Certificates of
each Class the Holders of which are required to consent to any such amendment
without the consent of the Holders of all Certificates of such Class then
outstanding.

                  Notwithstanding any contrary provision of this Agreement, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel addressed to the Trustee , which
opinion shall be an expense of the party requesting such


                                      -136-

<PAGE>



amendment but in any case shall not be an expense of the Trustee or the
Securities Administrator, to the effect that such amendment will not (other than
an amendment pursuant to clause (ii) of, and in accordance with, the preceding
paragraph) cause the imposition of any tax on REMIC I, REMIC II or REMIC III or
the Certificateholders or cause REMIC I, REMIC II or REMIC III to cease to
qualify as a REMIC at any time that any Certificates are outstanding. Further,
nothing in this Agreement shall require the Trustee to enter into an amendment
without receiving an Opinion of Counsel, satisfactory to the Trustee that (i)
such amendment is permitted and is not prohibited by this Agreement and that all
requirements for amending this Agreement (including any consent of the
applicable Certificateholders) have been complied with.

                  Promptly after the execution of any amendment to this
Agreement requiring the consent of Certificateholders, the Trustee shall furnish
written notification of the substance of such amendment to each
Certificateholder and each Rating Agency.

                  It shall not be necessary for the consent of
Certificateholders under this Section to approve the particular form of any
proposed amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner 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.

         Section 12.02     RECORDATION OF AGREEMENT; COUNTERPARTS.

                  To the extent permitted by applicable law, this Agreement is
subject to recordation in all appropriate public offices for real property
records in all of 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 Master Servicer shall effect such
recordation at the Trust's expense 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.

                  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 12.03     GOVERNING LAW.

                  THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE
OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE
CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT
REGARD TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF (OTHER THAN SECTION 5-1401 OF
THE GENERAL OBLIGATIONS LAWS).

         Section 12.04     INTENTION OF PARTIES.

                  It is the express intent of the parties hereto that the
conveyance of the Mortgage Notes, Mortgages, assignments of Mortgages, title
insurance policies and any modifications, extensions and/or assumption
agreements and private mortgage insurance policies relating to the Mortgage
Loans by the Seller to the Depositor, and by the Depositor to the Trustee be,
and be construed as, an absolute sale thereof to the Depositor or the Trustee,
as applicable. It is, further, not the intention of the parties that such
conveyance be deemed a pledge thereof by the Seller to the Depositor, or by the
Depositor to the Trustee. However, in the event that, notwithstanding the intent
of the parties, such assets are held to be the property of the Seller or the
Depositor, as applicable, or if for any other reason this Agreement is held or
deemed to create a security interest in such assets, then (i) this Agreement
shall be deemed to be a security agreement within the meaning of the Uniform
Commercial Code of the State of New York and (ii) each conveyance provided for
in this Agreement shall be deemed to be an assignment and a grant by the Seller
or the Depositor, as applicable , for the benefit of the Certificateholders, of
a security interest in all of the assets that constitute the Trust Fund, whether
now owned or hereafter acquired.

                  The Depositor for the benefit of the Certificateholders shall,
to the extent consistent with this Agreement, take such actions as may be
necessary to ensure that, if this Agreement were deemed to create a security
interest in the assets of the Trust Fund, such security interest would be deemed
to be a perfected security interest of first priority under applicable law and
will be maintained as such throughout the term of the Agreement.

         Section 12.05     NOTICES.

                  (a) The Trustee shall use its best efforts to promptly provide

                  (v) The final payment to Certificateholders.

                  (b) All directions, demands and notices hereunder shall be in

         Section 12.08     LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

                  The death or incapacity of any Certificateholder shall not

Certificateholder's legal representative or heirs to claim an accounting or to
take any action or commence any proceeding in any court for a petition or
winding up of the Trust Fund, or otherwise affect the rights, obligations and
liabilities of the parties hereto or any of them.

                  No Certificateholder shall have any right to vote (except as
provided herein) or in any manner otherwise control the operation and management

herein set forth or contained in the terms of the Certificates be construed so
as to constitute the Certificateholders from time to time as partners or members
of an association; nor shall any Certificateholder be under any liability to any

                  No Certificateholder shall have any right by virtue or by
availing itself of any provisions of this Agreement to institute any suit,
action or proceeding in equity or at law upon or under or with respect to this
Agreement, unless such Holder previously shall have given to the Trustee or the
Securities Administrator, as appropriate, a written notice of an Event of
Default and of the continuance thereof, as hereinbefore provided, the Holders of
Certificates evidencing not less than 25% of the Voting Rights evidenced by the
Certificates shall also have made written request to the Trustee or the
Securities Administrator, as appropriate to institute such action, suit or
proceeding in its own name as Trustee or the Securities Administrator, as
appropriate, hereunder and shall have offered to the Trustee or the Securities
Administrator, as appropriate, such reasonable indemnity as it may require
against the costs, expenses, and liabilities to be incurred therein or thereby,
and the Trustee or the Securities Administrator, as appropriate, 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; it being
understood and intended, and being expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more Holders of Certificates shall have any right in any manner whatever
by virtue or by availing itself or themselves of any provisions of this
Agreement to affect, disturb or prejudice the rights of the Holders of any other
of the Certificates, or to obtain or seek to obtain priority over or preference
to any other such Holder or to enforce any right under this Agreement, except in
the manner herein provided and for the common benefit of all Certificateholders.
For the protection and enforcement of the provisions of this Section 12.08, each
and every Certificateholder, the Trustee or the Securities Administrator shall
be entitled to such relief as can be given either at law or in equity.

         Section 12.09 INSPECTION AND AUDIT RIGHTS. The Master Servicer agrees
that, on reasonable prior notice, it will permit any representative of the
Depositor or the Trustee during the Master Servicer's normal business hours, to
examine all the books of account, records, reports and other papers of the
Master Servicer relating to the Mortgage Loans, to make copies and extracts
therefrom, to cause such books to be audited by independent certified public
accountants selected by the Depositor or the Trustee and to discuss its affairs,
finances and accounts relating to such Mortgage Loans with its officers,
employees and independent public accountants (and by this provision the Master
Servicer hereby authorizes such accountants to discuss with such representative
such affairs, finances and accounts), all at such reasonable times and as often
as may be reasonably requested. Any out-of-pocket expense incident to the
exercise by the Depositor or the Trustee of any right under this Section 12.09
shall be borne by the party requesting such inspection, subject to such party's
right to reimbursement hereunder (in the case of the Trustee, pursuant to
Section 10.05 hereof).

         Section 12.10     CERTIFICATES NONASSESSABLE AND FULLY PAID.

                  It is the intention of the Depositor that Certificateholders
shall not be personally liable for obligations of the Trust Fund, that the
interests in the Trust Fund represented by the Certificates shall be
nonassessable for any reason whatsoever, and that the Certificates, upon due
authentication thereof by the Trustee pursuant to this Agreement, are and shall
be deemed fully paid.

                                 SERIES 2003-AC4

         evidencing a fractional undivided interest in the distributions
         allocable to the Class A Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by BEAR STEARNS ASSET BACKED
         SECURITIES, INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Bear Stearns
Asset Backed Securities, Inc., the Master Servicer, the Trustee or the
Securities Administrator 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 Bear Stearns Asset Backed
Securities, Inc., the Master Servicer, the Trustee or the Securities
Administrator or any of their affiliates or any other person. None of Bear
Stearns Asset Backed Securities, 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
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences (collectively, the "Mortgage Loans")
sold by Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans
were sold by EMC Mortgage Corporation ("EMC") to BSABS. Wells Fargo Bank
Minnesota, National Association will


                                      A-1-2

<PAGE>



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

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

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

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

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of each Class of Certificates affected thereby evidencing over 50% of
the Voting Rights of such Class or Classes. 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 Percentage 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 Percentage 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 Depositor, 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 Depositor, the Master Servicer, the
Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate Stated Principal Balance of the Mortgage Loans is less than the
percentage of the aggregate Stated Principal Balance specified in the Agreement
of the Mortgage Loans at the Cut-off Date. The exercise of such right will
effect the early retirement of the


                                      A-1-4

<PAGE>



Certificates. In no event, however, will the Trust Fund created by the Agreement
continue beyond the expiration of 21 years after the death of certain persons
identified in the Agreement.

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

                                 SERIES 2003-AC4

         evidencing a fractional undivided interest in the distributions
         allocable to the Class A-IO Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by BEAR STEARNS ASSET BACKED
         SECURITIES, INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Bear Stearns
Asset Backed Securities, Inc., the Master Servicer, the Trustee or the
Securities Administrator 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 Bear Stearns Asset Backed
Securities, Inc., the Master Servicer, the Trustee or the Securities
Administrator or any of their affiliates or any other person. None of Bear
Stearns Asset Backed Securities, 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
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences (collectively, the "Mortgage Loans")
sold by Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans
were sold by EMC Mortgage Corporation ("EMC") to BSABS. Wells Fargo Bank
Minnesota, National Association will


                                      A-2-2

<PAGE>



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

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Certificate Notional Amount hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 25th day
of each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (each, a "Distribution Date"), commencing on the First
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last day (or if such last day is
not a Business Day, the Business Day immediately preceding such last day) of the
calendar month immediately preceding the month in which the Distribution Date
occurs, an amount equal to the product of the Percentage Interest evidenced by
this Certificate and the amount (of interest, if any) required to be distributed
to the Holders of Certificates of the same Class as this Certificate. The
Assumed Final Distribution Date is the Distribution Date in February 2006.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
Class A-IO Certificates have no Certificate Principal Balance. The Initial
Certificate Notional Balance of this Certificate is set forth above.

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

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such class or classes. 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 Percentage 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 Percentage 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 Depositor, 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 Depositor, the Master Servicer, the
Trustee or any such agent shall be affected by notice to the contrary.

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

Mortgage Corporation ("EMC") to BSABS. Wells Fargo Bank Minnesota, National

Servicer," which term includes any successors thereto under the Agreement
referred to below). The Trust Fund was created pursuant to the Pooling and

"Agreement"), among BSABS, as depositor (the "Depositor"), EMC Mortgage
Corporation as seller and company, Wells Fargo Bank Minnesota, National
Association, as Master Servicer and securities administrator (the "Securities

certain of the pertinent provisions of which is set forth hereafter. To the

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 Certificate Principal Balance hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 25th day

following Business Day (each, a "Distribution Date"), commencing on the First
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last day (or if such last day is
not a Business Day, the Business Day immediately preceding such last day) of the
calendar month immediately preceding the month in which the Distribution Date
occurs, an amount equal to the product of the Percentage 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.] [Interest on this Certificate will accrue from and including the
25th day of the calendar month preceding the month in which a Distribution Date
(as hereinafter defined) occurs (or, with respect to the first accrual period,
the Closing Date) to and including the 24th day of the calendar month in which
that Distribution Date occurs on the Certificate Principal Balance hereof at a
per annum rate equal to the Pass-Through Rate set forth above. The Trustee will
distribute on the 25th day of each month, or, if such 25th day is not a Business
Day, the immediately following Business Day (each, a "Distribution Date"),
commencing on the First Distribution Date specified above, to the Person in
whose name this Certificate is registered at the close of business on the
Business Day immediately preceding such Distribution Date, an amount equal to
the product of the Percentage Interest evidenced by this Certificate and the
amount (of interest and principal, if any) required to be distributed to the
Holders of Certificates of the same Class as this Certificate.] The Assumed
Final Distribution Date is the Distribution Date in the month following the
latest scheduled maturity date of any Mortgage Loan and is not likely to be the
date on which the Certificate Principal Balance of this Class of Certificates
will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.

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").
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 Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. 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 Percentage Interest
will be issued to the designated transferee.

         Each beneficial owner of a Certificate or any interest therein shall be
deemed to have represented, by virtue of its acquisition or holding of that
certificate or interest therein, that either (i) it is not a Plan or investing
with "Plan Assets", (ii) it has acquired and is holding such certificate in
reliance on the Exemption, and that it understands that there are certain
conditions to the availability of the Exemption, including that the certificate
must be rated, at the time of purchase, not lower than "BBB-" (or its
equivalent) by S&P, Fitch or Moody,s Investors Service, Inc., and the
certificate is so rated or (iii) (1) it is an insurance company, (2) the source
of funds used to acquire or hold the certificate or interest therein is an
"insurance company general account," as such term is defined in Prohibited
Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in Sections I
and III of PTCE 95-60 have been satisfied.

                  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 Percentage 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 Depositor, 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 Depositor, the Master Servicer,
the Trustee or any such agent shall be affected by notice to the contrary.

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

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

                                 SERIES 2003-AC4

         evidencing a fractional undivided interest in the distributions
         allocable to the Class B[A][B] Certificates with respect to a Trust
         Fund consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by BEAR STEARNS ASSET BACKED
         SECURITIES, INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Bear Stearns
Asset Backed Securities, Inc., the Master Servicer, the Trustee or the
Securities Administrator 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 Bear Stearns Asset Backed
Securities, Inc., the Master Servicer, the Trustee or the Securities
Administrator or any of their affiliates or any other person. None of Bear
Stearns Asset Backed Securities, 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
Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences (collectively, the "Mortgage Loans")
sold by Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans
were sold by EMC


                                      A-4-3

<PAGE>



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

                  [Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Certificate Principal Balance hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 25th day
of each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (each, a "Distribution Date"), commencing on the First
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last day (or if such last day is
not a Business Day, the Business Day immediately preceding such last day) of the
calendar month immediately preceding the month in which the Distribution Date
occurs, an amount equal to the product of the Percentage 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.] [Interest on this Certificate will accrue from and including the
25th day of the calendar month preceding the month in which a Distribution Date
(as hereinafter defined) occurs (or, with respect to the first accrual period,
the Closing Date) to and including the 24th day of the calendar month in which
that Distribution Date occurs on the Certificate Principal Balance hereof at a
per annum rate equal to the Pass-Through Rate set forth above. The Trustee will
distribute on the 25th day of each month, or, if such 25th day is not a Business
Day, the immediately following Business Day (each, a "Distribution Date"),
commencing on the First Distribution Date specified above, to the Person in
whose name this Certificate is registered at the close of business on the
Business Day immediately preceding such Distribution Date, an amount equal to
the product of the Percentage Interest evidenced by this Certificate and the
amount (of interest and principal, if any) required to be distributed to the
Holders of Certificates of the same Class as this Certificate.] The Assumed
Final Distribution Date is the Distribution Date in the month following the
latest scheduled maturity date of any Mortgage Loan and is not likely to be the
date on which the Certificate Principal Balance of this Class of Certificates
will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
initial Certificate Principal Balance of this Certificate is set forth

in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

shall be deemed to have represented, by virtue of its acquisition or holding of

of funds used to acquire or hold the certificate or interest therein is an
"insurance company general account," as such term is defined in Prohibited
Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in Sections I
and III of PTCE 95-60 have been satisfied.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of (A) the maturity or other

         evidencing a fractional undivided interest in the distributions
         allocable to the Class C Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         fixed interest rate mortgage loans sold by BEAR STEARNS ASSET BACKED
         SECURITIES, INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Bear Stearns
Asset Backed Securities, Inc., the Master Servicer, the Trustee or the
Securities Administrator 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 Bear Stearns Asset Backed

Administrator or any of their affiliates or any other person. None of Bear
Stearns Asset Backed Securities, 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 Percentage Interest evidenced hereby in the beneficial ownership
interest of Certificates of the same Class as this Certificate in a trust (the
"Trust Fund") generally consisting of conventional first lien, fixed rate
mortgage loans secured by one- to four- family residences (collectively, the
"Mortgage Loans") sold by Bear Stearns Asset Backed Securities, Inc. ("BSABS").
The Mortgage Loans were sold by EMC

<PAGE>



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

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Trustee, the Securities Administrator or the
Master Servicer in their respective capacities as such), together with copies of
the written certification(s) of the Holder of the Certificate desiring to effect
the transfer and/or such Holder's prospective transferee upon which such Opinion
of Counsel is based. Neither the Depositor 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 Depositor, the Seller and the Master Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No transfer of this Class C Certificate will be made unless
the Trustee and the Securities Administrator have received either (i) an opinion
of counsel acceptable to and in form and substance satisfactory to the Trustee,
the Securities Administrator and the Master Servicer with


                                      A-5-4

<PAGE>



respect to the permissibility of such transfer under the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), and Section 4975 of the
Internal Revenue Code (the "Code") and stating, among other things, that the
transferee's acquisition of a Class C Certificate will not constitute or result
in a non-exempt prohibited transaction under Section 406 of ERISA or Section
4975 of the Code and will not subject the Master Servicer, the Trustee or the
Securities Administrator to any obligation or liability in addition to those
undertaken in the agreement or (ii) a representation letter, in the form as
described by the Agreement, stating that the transferee is not an employee
benefit or other plan subject to the prohibited transaction provisions of ERISA
or Section 4975 of the Code (a "Plan"), or any other person (including an
investment manager, a named fiduciary or a trustee of any Plan) acting, directly
or indirectly, on behalf of or purchasing any Certificate with "plan assets" of
any Plan.

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

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. 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 Percentage 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-5-5

<PAGE>



Certificates evidencing the same Class and in the same aggregate Percentage
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 Depositor, 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 Depositor, the Master Servicer,
the Trustee or any such agent shall be affected by notice to the contrary.

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

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

         consisting primarily of a pool of conventional one- to four-family

the Percentage Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of conventional first lien, fixed rate mortgage loans
secured by one- to four- family residences (collectively, the "Mortgage Loans")
sold by Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans
were sold by EMC

<PAGE>



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

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit E and either F
or G, as applicable, and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration or
qualification (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Trustee, the Securities Administrator or the
Master Servicer in their respective capacities as such), together with copies of
the written certification(s) of the Holder of the Certificate desiring to effect
the transfer and/or such Holder's prospective transferee upon which such Opinion
of Counsel is based. Neither the Depositor 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 Depositor, the Seller and the Master Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  No transfer of this Class P Certificate will be made unless
the Trustee and the Securities Administrator have received either (i) an opinion
of counsel acceptable to and in form and substance satisfactory to the Trustee,
the Securities Administrator and the Master Servicer with


                                      A-6-4

<PAGE>



respect to the permissibility of such transfer under the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), and Section 4975 of the
Internal Revenue Code (the "Code") and stating, among other things, that the
transferee's acquisition of a Class P Certificate will not constitute or result
in a non-exempt prohibited transaction under Section 406 of ERISA or Section
4975 of the Code and will not subject the Master Servicer, the Trustee or the
Securities Administrator to any obligation or liability in addition to those
undertaken in the agreement or (ii) a representation letter, in the form as
described by the Agreement, stating that the transferee is not an employee
benefit or other plan subject to the prohibited transaction provisions of ERISA
or Section 4975 of the Code (a "Plan"), or any other person (including an
investment manager, a named fiduciary or a trustee of any Plan) acting, directly
or indirectly, on behalf of or purchasing any Certificate with "plan assets" of
any Plan.

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

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. 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 Percentage 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-6-5

<PAGE>



Certificates evidencing the same Class and in the same aggregate Percentage
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 Depositor, 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 Depositor, the Master Servicer,
the Trustee or any such agent shall be affected by notice to the contrary.

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

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

provided, the amendment thereof and the modification of the rights and
obligations of the Depositor and the rights of the Certificateholders under the
Agreement from time to time by the parties thereto with the consent of the
Holders of the Class or Classes of Certificates affected thereby evidencing over
50% of the Voting Rights of such Class or Classes. 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 Percentage 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 Percentage 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 Depositor, 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 Depositor, the Master Servicer, the
Trustee or any such agent shall be affected by notice to the contrary.

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

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

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

Ladies and Gentlemen:

         ______________ (the "Purchaser") intends to purchase from
______________ (the "Seller") $_________ Initial Certificate Principal Balance
of Asset-Backed Certificates, Series 2003-AC4, Class _____ (the "Certificates"),
issued pursuant to the Pooling and Servicing Agreement (the "Pooling and
Servicing Agreement"), dated as of August 1, 2003 among Bear Stearns Asset
Backed Securities, Inc., as depositor (the "Depositor"), EMC Mortgage

Bank, as trustee (the "Trustee"). All terms used herein and not otherwise
defined shall have the meanings set forth in the Pooling and Servicing
Agreement. The Purchaser hereby certifies, represents and warrants to, and
covenants with, the Depositor and the Trustee that:

                           1. The Purchaser understands that (a) the
                  Certificates have not been and will not be registered or

                  pursuant to the provisions of the Act or any state securities

                  qualification is available, (d) the Pooling and Servicing
                  Agreement contains restrictions regarding the transfer of the
                  Certificates and (e) the Certificates will bear a legend to
                  the foregoing effect.

                           2. The Purchaser is acquiring the Certificates for
                  its own account for investment only and not with a view to or
                  for sale in connection with any distribution thereof in any
                  manner that would violate the Act or any applicable state
                  securities laws.

                           3. The Purchaser is (a) a substantial, sophisticated
                  institutional investor having such knowledge and experience in
                  financial and business matters, and, in particular, in such
                  matters related to securities similar to the Certificates,
                  such that it is capable of evaluating the merits and risks of
                  investment in the Certificates, (b) able to bear the economic
                  risks of such an investment and (c) an "accredited investor"
                  within the meaning of Rule 501 (a) promulgated pursuant to the
                  Act.

                           4. The Purchaser has been furnished with, and has had
                  an opportunity to review (a) [a copy of the Private Placement
                  Memorandum, dated ______, 2003, relating to the Certificates
                  (b)] a copy of the Pooling and Servicing Agreement and [(b)]
                  [(c)] such other information concerning the Certificates, the
                  Mortgage Loans and the Depositor as has been requested by the
                  Purchaser from the Depositor or the Seller and is relevant to
                  the Purchaser's decision to purchase the Certificates. The
                  Purchaser has had any questions arising from such review
                  answered by the Depositor or the Seller to the satisfaction of
                  the Purchaser. [If the Purchaser did not purchase the
                  Certificates from the Seller in connection with the initial
                  distribution of the Certificates and was provided with a copy
                  of the Private Placement Memorandum (the "Memorandum")
                  relating to the original sale (the "Original Sale") of the
                  Certificates by the Depositor, the Purchaser acknowledges that
                  such Memorandum was provided to it by the Seller, that the
                  Memorandum was prepared by the Depositor solely for use in
                  connection with the Original Sale and the Depositor did not
                  participate in or facilitate in any way the purchase of the
                  Certificates by the Purchaser from the Seller, and the
                  Purchaser agrees that it will look solely to the Seller and
                  not to the Depositor with respect to any damage, liability,
                  claim or expense arising out of, resulting from or in
                  connection with (a) error or omission, or alleged error or
                  omission, contained in the Memorandum, or (b) any information,
                  development or event arising after the date of the
                  Memorandum.]

                           5. The Purchaser has not and will not nor has it
                  authorized or will it authorize any person to (a) offer,
                  pledge, sell, dispose of or otherwise transfer any
                  Certificate, any interest in any Certificate or any other
                  similar security to any person in any manner, (b) solicit any
                  offer to buy or to accept a pledge, disposition of other
                  transfer of any Certificate, any interest in any Certificate
                  or any other similar security from any person in any manner,
                  (c) otherwise approach or negotiate with respect to any
                  Certificate, any interest in any Certificate or any other
                  similar security with any person in any manner, (d) make any
                  general solicitation by means of general advertising or in any
                  other manner or (e) take any other action, that (as to any of
                  (a) through (e) above) would constitute a distribution of any
                  Certificate under the Act, that would render the disposition
                  of any Certificate a violation of Section 5 of the Act or any
                  state securities law, or that would require registration or
                  qualification pursuant thereto. The Purchaser will not sell or
                  otherwise transfer any of the Certificates, except in
                  compliance with the provisions of the Pooling and Servicing
                  Agreement.

                  Section 2.1. CUSTODIAN TO ACT AS AGENT: ACCEPTANCE OF MORTGAGE
FILES. The custodian, as the duly appointed agent of the Trustee for these
purposes, acknowledges (subject to any exceptions noted in the Initial
Certification referred to in Section 2.3(a) receipt of the Mortgage Files
relating to the Mortgage Loans identified on the schedule attached hereto (the
"Mortgage Files") and declares that it holds and will hold such Mortgage Files
as agent for the Trustee, in trust, for the use and benefit of all present and
future Certificateholders.

                  Section 2.2. RECORDATION OF ASSIGNMENTS. If any Mortgage File
includes one or more assignments of Mortgage that have not been recorded
pursuant to the provisions of Section 2.01 of the Pooling and Servicing
Agreement and the related Mortgage Loan is not a MOM Loan or the related
Mortgaged Properties are located in jurisdictions specifically excluded by the
Opinion of Counsel delivered to the Trustee pursuant to Section 2.01 of the
Pooling and Servicing Agreement, each such assignment shall be delivered by the
Custodian to the Seller for the purpose of recording it in the appropriate
public office for real property records, and the Seller, 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 Seller and the Trustee an Initial Certification in the form annexed
hereto as Exhibit One evidencing receipt (subject to any exceptions noted
therein) of a Mortgage File for each of the Mortgage Loans listed on the
Schedule attached hereto (the "Mortgage Loan Schedule").

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

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

                  (d) In reviewing the Mortgage Files as provided herein and in
the Pooling and Servicing Agreement, the Custodian shall make no representation
as to and shall not be responsible to verify (i) the validity, legality,
enforceability, due authorization, recordability, sufficiency or


                                       K-2

genuineness of any of the documents included in any Mortgage File or (ii) the
collectibility, insurability, effectiveness or suitability of any of the
documents in any Mortgage File.

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

                  Section 2.4. NOTIFICATION OF BREACHES OF REPRESENTATIONS AND
WARRANTIES. Upon discovery by the Custodian of a breach of any representation or
warranty made by the Depositor 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 Depositor, 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 Seller has
repurchased a Mortgage Loan pursuant to Article II of the Pooling and Servicing
Agreement, and a request for release (a "Request for Release") confirming that
the purchase price therefore has been deposited in the Master Servicer
Collection Account or the Distribution Account, then the Custodian agrees to
promptly release to the Seller the related Mortgage File.

                  Upon the Custodian's receipt of a Request for Release
substantially in the form of Exhibit H to the Pooling and Servicing Agreement
signed by a Servicing Officer of the Company or the Servicer, as applicable,
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 Company or the Servicer, as applicable, the
related Mortgage File. The Depositor shall deliver to the Custodian and the
Custodian agrees to review in accordance with the provisions of their Agreement
the Mortgage Note and other documents constituting the Mortgage File with
respect to any Replacement 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 or LPMI Policy, the Company or the Servicer, as
applicable, 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 Company or the Servicer, as applicable, 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 Company or the Servicer, as applicable. The Company or the
Servicer, as applicable, shall cause each Mortgage File or any document therein
so released to be returned to the Custodian when the need therefore by the
Company or the Servicer, as applicable, no longer exists, unless (i) the
Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the
Mortgage Loan have been deposited in the Master Servicer Collection Account or
the Distribution Account or (ii) the Mortgage File or such document has been
delivered to an attorney, or to a public trustee or other public official as
required by law, for purposes of initiating or pursuing legal action or other
proceedings for the foreclosure of the Mortgaged Property either judicially or
non-judicially, and the Company or the Servicer, as applicable, has delivered to
the Custodian a certificate of a


                                       K-3

<PAGE>



Servicing Officer certifying as to the name and address of the Person to which
such Mortgage File or such document was delivered and the purpose or purposes of
such delivery.

                  At any time that the Company or the Servicer is required to
deliver to the Custodian a Request for Release, the Company or the Servicer, as
applicable, shall deliver two copies of the Request for Release if delivered in
hard copy or the Company or the Servicer, as applicable, may furnish such
Request for Release electronically to the Custodian, in which event the
Servicing Officer transmitting the same shall be deemed to have signed the
Request for Release. In connection with any Request for Release of a Mortgage
File because of a repurchase of a Mortgage Loan, such Request for Release shall
be accompanied by an assignment of mortgage, without recourse, representation or
warranty from the Trustee to the Seller (unless such Mortgage Loan is a MOM
Loan) and the related Mortgage Note shall be endorsed without recourse,
representation or warranty by the Trustee and be returned to the 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 Company or the
Servicer, as applicable.

                  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 Pooling
and Servicing Agreement or National City Servicing Agreement, shall cause the
Company or the Servicer, as applicable, 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 Depositor,
the Servicer or the Master Servicer or otherwise released from the possession of
the Custodian.

                  Section 3.2. RESERVED.

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

                  Section 3.4. MASTER SERVICER TO PAY CUSTODIAN'S FEES AND
EXPENSES. The Master Servicer covenants and agrees to pay to the Custodian from
time to time, and the Custodian shall be entitled to, reasonable compensation
for all services rendered by it in the exercise and performance of any of the
powers and duties hereunder of the Custodian, and the Master Servicer will pay
or reimburse the Custodian upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Custodian in accordance with
any of the provisions of this Agreement (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ), except any such expense, disbursement or advance as
may arise from its negligence or bad faith or to the extent that such cost or
expense is indemnified by the Depositor 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 Depositor, 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 upon 60 days
prior written notice to Custodian. 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 Servicers, the Company and the Depositor.

                  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 Depositor 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 Depositor
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


                                       K-5

a combined capital and surplus of at least $15,000,000 and is qualified to do
business in the jurisdictions in which it will hold any Mortgage File.



                                   ARTICLE IV.
                            MISCELLANEOUS PROVISIONS

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