          POOLING AND SERVICING AGREEMENT, dated as of April 1, 2002, among BEAR
STEARNS ASSET BACKED SECURITIES, INC., a Delaware corporation, as depositor (the
"Depositor"), EMC MORTGAGE CORPORATION, a Delaware corporation, as seller (in
such capacity, the "Seller") and as company (in such capacity, the "Company"),
WELLS FARGO BANK MINNESOTA, NATIONAL ASSOCIATION, a national banking
association, as master servicer (in such capacity, the "Master Servicer") and as
securities administrator (in such capacity, the "Securities Administrator") and
BANK ONE, NATIONAL ASSOCIATION, a national banking association, not in its
individual capacity, but solely as trustee (the "Trustee").

                              PRELIMINARY STATEMENT

          The Depositor is the owner of the Trust Fund that is hereby conveyed
to the Trustee in return for the Certificates.

                                     REMIC I

     As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans (other than the
Prepayment Charges and the related Reserve Account) and certain other related
assets subject to this Agreement as a real estate mortgage investment conduit (a
"REMIC") for federal income tax purposes, and such segregated pool of assets
will be designated as "REMIC I." The Class R-1 Certificates will represent the
sole class of "residual interests" in REMIC I for purposes of the REMIC
Provisions (as defined herein) under federal income tax law and will have an
initial Certificate Principal Balance of $50.00. The following table irrevocably
sets forth the designation, the Uncertificated REMIC I Pass-Through Rate, the
initial Uncertificated Principal Balance, and solely for purposes of satisfying
Treasury regulation Section 1.860G-1(a)(4)(iii), the "latest possible maturity
date" for each of the REMIC I Regular Interests. None of the REMIC I Regular
Interests will be certificated. For federal income tax purposes the Prepayment
Charges will be treated as a "strip" under Section 1286 of the Code and will be
included in the Trust Fund but not in any REMIC.

                                          Uncertificated

-------------------
(1)  Solely for purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
     regulations, the Distribution Date in the month following the maturity date
     for the Mortgage Loan with the latest maturity date has been designated as
     the "latest possible maturity date" for each REMIC I Regular Interest that
     represents one or more of the "regular interests" in REMIC I.

(2)  REMIC I Regular Interest LTI-X1 will not have an Uncertificated Principal
     Balance and is not entitled to receive distributions of principal. Instead,
     interest will accrue on an Uncertificated Notional Balance equal to the
     aggregate Stated Principal Balance of the Mortgage Loans.

(3)  The Uncertificated REMIC I Pass-Through Rate for Uncertificated REMIC I
     Regular Interest LTI-X1 shall be the product the excess of (A) the weighted
     average of the Net Mortgage Rates on the Non-Discount Mortgage Loans over
     (b) 7.000% per annum.

(4)  REMIC I Regular Interest LTI-PO is a principal only certificate and will
     not be entitled to distributions of interest.

                                    REMIC II
                                    --------

     As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the REMIC I Regular Interests as a REMIC
for federal income tax purposes, and such segregated pool of assets will be
designated as "REMIC II". The Class R-2 Certificates will represent the sole
class of "residual interests" in REMIC II for purposes of the REMIC Provisions
and will have an initial Certificate Principal Balance of $50.00.

     The following table irrevocably sets forth the Class designation,
Pass-Through Rate and Initial Certificate Principal Balance for each Class of
Certificates that represents one or more of the "regular interests" in REMIC II
created hereunder:

this Agreement, the following words and phrases, unless the context otherwise
requires, shall have the following meanings:

          ACCEPTED MASTER SERVICING PRACTICES: With respect to any Mortgage
Loan, as applicable, either (a) those customary mortgage servicing practices of
prudent mortgage servicing institutions that master service mortgage loans of
the same type and quality as such Mortgage Loan in the jurisdiction where the
related Mortgaged Property is located, to the extent applicable to the Trustee
or the Master Servicer (except in its capacity as successor to the Company or a
Servicer), or (b) as provided in Section 3.01 hereof or Section 4.01 of the
related Servicing Agreement, but, in each case, in no event below the standard
set forth in clause (a).

          ACCEPTED SERVICING PRACTICES: With respect to each EMC Mortgage Loan,
those mortgage servicing practices (including collection procedures) that are in
accordance with all applicable statutes, regulations and prudent mortgage
banking practices for similar mortgage loans.

          ACCOUNT: The Distribution Account, the Master Servicer Collection
Account, Reserve Account and any Protected Account.

          ACCRUAL PERIOD: With respect to the Certificates (other than the

on the basis of a 360-day year consisting of twelve 30-day months.

          ACCRUED CERTIFICATE INTEREST: With respect to the Certificates (other

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

                                      -39-
<PAGE>

delivery as specified above, the Depositor may deliver 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
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 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 (a) any assignment in any jurisdiction under the laws of
which, as evidenced by an Opinion of Counsel 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 the mortgagee of record solely as nominee for Seller and its
successor 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 Trustee shall cause each such previously
unrecorded assignment to be submitted for recording as specified above at the
expense of the Trust pursuant to Section 10.05. In the event a Mortgage File is
released to the Company or the related Servicer as a result of such Person
having completed a Request for Release, the Trustee 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 any 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.

     Section 2.02  ACCEPTANCE OF THE MORTGAGE LOANS.

          (a) The Trustee acknowledges receipt of, subject to the further review
and exceptions reported by the Trustee pursuant to the procedures described
below, the documents (or

                                      -40-
<PAGE>

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 the Master Servicer 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 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 the Master Servicer, a Final Certification
substantially in the form annexed hereto as Exhibit C-3. 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

                                      -41-
<PAGE>

(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 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 will release to the Seller the related Mortgage File and the
Trustee shall execute and deliver all instruments of transfer or assignment,
without recourse, furnished to it by the 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 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.

          (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

     Delaware and is duly authorized and qualified to transact any and all
     business contemplated by this Agreement to be conducted by the Seller in

                                      -44-
<PAGE>

          (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

     adversely affect the execution, delivery or enforceability of this

          (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, 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

                                      -45-
<PAGE>

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 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.

                                      -46-
<PAGE>

          (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 applicable
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 National City Subservicing 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 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

                                      -47-
<PAGE>

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 an 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. 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. Except with respect to one Mortgage Loan
with a Cut-off Date Principal Balance of $450,104.67 (representing 0.155% of the
Mortgage Loans by the aggregate Cut-off Date Principal Balance), the Mortgagor
has not

                                      -48-
<PAGE>

notified the Seller and the Seller has no knowledge of any relief requested or
allowed to the Mortgagor under the Soldiers and Sailors Civil Relief Act of
1940.

          (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.

          (HH) [Reserved]

                                      -49-
<PAGE>

          (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) As of the Cut-off Date, none of the Mortgage Loans were subject
to the Home Ownership and Equity Protection Act of 1994 ("HOEPA").

          (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 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

                                      -50-
<PAGE>

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. 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 shall release to the Seller the
Mortgage File relating to such Deleted Mortgage Loan and held for the benefit of
the Certificateholders and 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, 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
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, 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

                                      -51-
<PAGE>

occurred and is continuing shall constitute the sole remedies against the Seller
respecting such breach available to the 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

     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
     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,

                                      -52-
<PAGE>

     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 or REMIC II or contributions after the Closing Date, as defined in
sections 860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause any
either REMIC I or REMIC II 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 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 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

                                      -53-
<PAGE>

pursuant hereto 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.

                                      -55-

     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

                                      -56-
<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 9.04, 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

                                      -57-
<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

                                      -58-
<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
constitute a Servicing Advance. 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.

                                      -59-

     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
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 such costs and

                                      -60-
<PAGE>

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 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 (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 or REMIC II as defined in section 860F of the Code or cause either REMIC I or
REMIC II 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 either REMIC I or REMIC II to the
imposition of any federal, state or local income taxes on

                                      -61-
<PAGE>

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 income and gain
net of any losses realized from Permitted Investments with respect to funds in
or credited to the 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 the Company pursuant to Section 5.02. The Company shall be
required to pay all 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.

     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.

                                      -63-

          The Company will deliver to the Master Servicer not later than 90 days
following the end of each fiscal year of the Company beginning in 2003, an
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.

     Section 3.14 ANNUAL INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS' SERVICING
                  REPORT.

          Not later than 120 days following the end of each fiscal year of the
Company, the Company at its expense shall cause a firm of independent public
accountants which is a member of the American Institute of Certified Public
Accountants to furnish a statement to the Master Servicer to the effect that
such firm has 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
firm shall believe to be immaterial,(ii) such other exceptions as shall be set
forth in such statement and (iii) such exceptions that the Uniform Single
Attestation Program for Mortgage Bankers requires it to report.

     Section 3.15 BOOKS AND RECORDS.

          The Company shall be responsible for maintaining, and shall 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 reflect the
ownership of the EMC Mortgage Loans by the Trust. In particular, the 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
upon demand, evidence of compliance with all federal, state and local laws,
rules and regulations. To the extent that original documents are not required
for purposes of realization of Liquidation Proceeds or Insurance Proceeds,
documents maintained by the Company may be in the form of microfilm or
microfiche or such other reliable means of recreating original documents,
including, but not limited to, optical imagery techniques so long as the Company
complies with the requirements of Accepted Servicing Practices.

          The Company shall maintain with respect to each EMC Mortgage Loan and
shall make available for inspection by the Master Servicer and the Trustee the
related servicing file during the time such EMC Mortgage Loan is subject to this
Agreement and thereafter in accordance with applicable law.

                                   ARTICLE IV

        ADMINISTRATION AND SERVICING OF MORTGAGE LOANS BY MASTER SERVICER

     Section 4.01 MASTER SERVICER. The Master Servicer shall supervise, monitor
and oversee the obligation of the Company and the Servicers to service and
administer their respective Mortgage Loans in accordance with the terms of this
Agreement and the applicable Servicing Agreements 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 each Servicer as necessary from
time-to-time to carry out the Master Servicer's obligations hereunder, shall
receive, review and evaluate all reports, information and other data provided to
the Master Servicer by the Company and each Servicer and shall cause the Company
and each Servicer to perform and observe the covenants, obligations and
conditions to be performed or observed by such Person under this Agreement and
the applicable Servicing Agreement. The Master Servicer shall independently and
separately monitor the Company and each Servicer's servicing activities with
respect to each related Mortgage Loan, reconcile the results of such monitoring
with such information provided in the previous sentence on a monthly basis and
coordinate corrective adjustments to the Company's, the Servicers' 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 Servicers to the Protected Accounts pursuant to this Agreement and the
Servicing Agreements.

     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 Servicers and the Master
Servicer to service and administer the related Mortgage Loans and REO Property.

     The Trustee and the Securities Administrator shall provide access to the
records and documentation in possession of the Trustee or the Securities
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

                                      -65-
<PAGE>

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

     Section 4.03 MONITORING OF SERVICERS. (a) The Master Servicer shall be
responsible for reporting to the Trustee and the Seller the compliance by the
Company and each Servicer with its duties under this Agreement and the related
Servicing Agreement. In the review of the Company's and each Servicer's
activities, the Master Servicer may rely upon an Officer's Certificate of the
Company and the 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 a Servicer
should be terminated in accordance with this Agreement or the Servicing
Agreement, or that a notice should be sent pursuant to this Agreement or such
Servicing Agreement with respect to the occurrence of an event that, unless
cured, would constitute grounds for such termination, the Master Servicer shall
notify the Seller and the Trustee thereof and the Master Servicer shall issue
such notice or take such other action as it deems appropriate.

     (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of the Company under this
Agreement and each Servicer under the related Servicing Agreement, and shall, in
the event that the Company or a 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 Servicing Agreements
and the pursuit of other appropriate remedies, shall be in such form and carried
out to such an extent and at such time as the Master Servicer, in its good faith
business judgment, would require were it the owner of the related Mortgage
Loans. The Master Servicer shall pay the costs of such enforcement at its own
expense, subject to its right of reimbursement pursuant to the provisions of
this Agreement or the applicable Servicing Agreement, provided that the Master
Servicer shall not be required to prosecute or defend any legal action except

                                      -66-
<PAGE>

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 a Servicer, appointment of a
successor Servicer or the transfer and assumption of servicing by the Master
Servicer with respect to this Agreement or any Servicing Agreement (including,
without limitation, (i) all legal costs and expenses and all due diligence costs
and expenses associated with an evaluation of the potential termination of the
Company or such 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 each 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 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 any Servicer to) knowingly
or intentionally take any action, or fail to take (or fail to cause to be taken)
any action reasonably within its control and the scope of duties more
specifically set forth herein, that, under the REMIC Provisions, if taken or not
taken, as the case may be, would cause REMIC I or REMIC II to fail to qualify as
a REMIC or

                                      -67-
<PAGE>

result in the imposition of a tax upon the Trust Fund (including but not limited
to the tax on prohibited transactions as defined in Section 860F(a)(2) of the
Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the
Code) unless the Master Servicer has received an Opinion of Counsel (but not at
the expense of the Master Servicer) to the effect that the contemplated action
will not would cause REMIC I or REMIC II to fail to qualify as a REMIC or result
in the imposition of a tax upon REMIC I or REMIC II, as the case may be. The
Trustee shall furnish the Master Servicer, upon written request from a Servicing
Officer, with any powers of attorney empowering the Master Servicer, the Company
or any Servicer to execute and deliver instruments of satisfaction or
cancellation, or of partial or full release or discharge, and to foreclose upon
or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in
any court action relating to the Mortgage Loans or the Mortgaged Property, in
accordance with the applicable Servicing Agreement and this Agreement, and the
Trustee shall execute and deliver such other documents, as the Master Servicer
may request, to enable the Master Servicer to master service and administer the
Mortgage Loans and carry out its duties hereunder, in each case in accordance
with Accepted Master Servicing Practices (and the Trustee shall have no
liability for misuse of any such powers of attorney by the Master Servicer, the
Company or any Servicer). If the Master Servicer or the Trustee has been advised
that it is likely that the laws of the state in which action is to be taken
prohibit such action if taken in the name of the Trustee or that the Trustee
would be adversely affected under the "doing business" or tax laws of such state
if such action is taken in its name, the Master Servicer shall join with the
Trustee in the appointment of a co-trustee pursuant to Section 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 applicable Servicing Agreement, to the extent
Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer
shall cause the Company and the Servicers to enforce such clauses in accordance
with this Agreement or the applicable Servicing Agreement. If applicable law
prohibits the enforcement of a due-on-sale clause or such clause is otherwise
not enforced in accordance with this Agreement or the applicable 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 applicable 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 any
Servicer of a notification that payment in full has been escrowed in a manner
customary for such purposes for payment to Certificateholders on the next
Distribution Date, the Company or the related Servicer will, if required under
the applicable Servicing Agreement, promptly furnish to the Custodian, on behalf
of the Trustee, two copies of a certification substantially in the form of
Exhibit 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 maintained by the Company or the
applicable Servicer pursuant to Article V or by the applicable Servicer pursuant
to its Servicing Agreement have been or will be so deposited) and shall request
that the Custodian, on behalf of the Trustee, deliver to the Company or the
applicable Servicer the related Mortgage File. Upon receipt of such
certification and request, the Custodian, on behalf of the

                                      -68-
<PAGE>

Trustee, shall promptly release the related Mortgage File to the Company or the
applicable Servicer and the Trustee and Custodian shall have no further
responsibility with regard to such Mortgage File. Upon any such payment in full,
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)
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 applicable
Servicing Agreement, the Trustee shall execute such documents as shall be
prepared and furnished to the Trustee by the Company, a Servicer or the Master
Servicer (in form reasonably acceptable to the Trustee) and as are necessary to
the prosecution of any such proceedings. The Custodian, on behalf of the
Trustee, shall, upon the request of the Company, a Servicer or the Master
Servicer, and delivery to the Custodian, on behalf of the Trustee, of two copies
of a request for release signed by a Servicing Officer substantially in the form
of Exhibit 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.

     Section 4.08 DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF MASTER SERVICER,
                  COMPANY AND SERVICER TO BE HELD FOR TRUSTEE.

     (a) The Master Servicer shall transmit and the Company or the related
Servicer (to the extent required by this Agreement or the applicable Servicing
Agreement) shall transmit to the Trustee or Custodian such documents and
instruments coming into the possession of such Person from time to time as are
required by the terms hereof, or in the case of the Servicers, the applicable
Servicing Agreement, to be delivered to the Trustee or Custodian. Any funds
received by the Master Servicer, the Company or by a Servicer in respect of any
Mortgage Loan or which otherwise are collected by the Master Servicer, the
Company or by a Servicer as Liquidation Proceeds or Insurance Proceeds in
respect of any Mortgage Loan shall be held for the benefit of the Trustee and
the Certificateholders subject to the Master Servicer's right to retain or
withdraw from the Master Servicer Collection Account the Master Servicing Fee
and other amounts provided in this Agreement, and to the right of the Company
and the related Servicer to retain its Servicing Fee and other amounts as
provided in this Agreement or the applicable Servicing Agreement. The Master
Servicer shall, and (to the extent provided in this Agreement or the applicable
Servicing Agreement) shall cause the Company and each Servicer to, provide
access to information and documentation regarding the Mortgage Loans to the
Trustee, its agents and accountants at any time upon reasonable request and
during normal business hours, and to Certificateholders that are savings and
loan

                                      -69-
<PAGE>

associations, banks or insurance companies, the Office of Thrift Supervision,
the FDIC and the supervisory agents and examiners of such Office and Corporation
or examiners of any other federal or state banking or insurance regulatory
authority if so required by applicable regulations of the Office of Thrift
Supervision or other regulatory authority, such access to be afforded without
charge but only upon reasonable request in writing and during normal business
hours at the offices of the Master Servicer designated by it. In fulfilling such
a request the Master Servicer shall not be responsible for determining the
sufficiency of such information.

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

     Section 4.09 STANDARD HAZARD INSURANCE AND FLOOD INSURANCE POLICIES.

     (a) For each Mortgage Loan, the Master Servicer shall enforce any
obligation of the Company and the related Servicer under this Agreement or the
applicable 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 applicable Servicing Agreement and that no earthquake or other additional
insurance is to be required of any Mortgagor or to be maintained on property
acquired in respect of a defaulted loan, other than pursuant to such applicable
laws and regulations as shall at any time be in force and as shall require such
additional insurance.

     (b) Pursuant to 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 any
Servicer, under any insurance policies (other than amounts to be applied to the
restoration or repair of the property subject to the related Mortgage or
released to the Mortgagor in accordance with this Agreement or the applicable
Servicing Agreement) 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 any Servicer in maintaining any such insurance if the Mortgagor defaults in
its obligation to do so shall be added to the amount owing under the Mortgage
Loan where the terms of the Mortgage Loan so permit; provided, however, that the
addition of any such cost shall not be taken into account for purposes of
calculating the distributions to be made to Certificateholders and shall be
recoverable by the Master Servicer, the Company or the related Servicer pursuant
to Sections 5.02, 5.03, 5.04 and 5.06, as applicable.

     Section 4.10 PRESENTMENT OF CLAIMS AND COLLECTION OF PROCEEDS. The Master
Servicer shall (to the extent provided in this Agreement and the applicable
Servicing Agreement) cause the Company or the related Servicer to, prepare and
present on behalf of the Trustee and the

                                      -70-
<PAGE>

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

     Section 4.11 MAINTENANCE OF THE PRIMARY MORTGAGE INSURANCE POLICIES.

     (a) The Master Servicer shall not take, or permit the Company or any
Servicer (to the extent such action is prohibited under this Agreement or the
applicable Servicing Agreement) to take, any action that would result in
noncoverage under any applicable Primary Mortgage Insurance Policy of any loss
which, but for the actions of the Master Servicer, the Company or such Servicer,
would have been covered thereunder. The Master Servicer shall use its best
reasonable efforts to cause the Company and each 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 lender-paid Primary Mortgage Insurance 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
any 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 to be kept in force hereunder except in accordance
with the provisions of this Agreement and the related Servicing Agreement, as
applicable.

     (b) The Master Servicer agrees to cause the Company and each 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.

     Section 4.12 TRUSTEE TO RETAIN POSSESSION OF CERTAIN INSURANCE POLICIES AND
                  DOCUMENTS.

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

                                      -71-
<PAGE>

terms and conditions of this Agreement. The Master Servicer shall promptly
deliver or cause to be delivered to the Trustee (or the Custodian, as directed
by the Trustee), upon the execution or receipt thereof the originals of any
Primary Mortgage Insurance Policies, any certificates of renewal, and such other
documents or instruments that constitute portions of the Mortgage File that come
into the possession of the Master Servicer from time to time.

     Section 4.13 REALIZATION UPON DEFAULTED MORTGAGE LOANS. The Master Servicer
shall cause the Company and each Servicer (to the extent required under this
Agreement and the related Servicing Agreement) to foreclose upon, repossess or
otherwise comparably convert the ownership of Mortgaged Properties securing such
of the Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments, all
in accordance with this Agreement or the applicable Servicing Agreement.

     Section 4.14 COMPENSATION FOR THE MASTER SERVICER.

          The Master Servicer shall be entitled to the Master Servicing Fee on
each Distribution Date as compensation for the performance of its obligations
hereunder. In addition, pursuant to Article V all income and gain realized from
any investment of funds in the Distribution Account and the Master Servicer
Collection Account shall be for the benefit of the Master Servicer as additional
compensation. The Master Servicer will be entitled to retain, as additional
compensation, any interest remitted by a Servicer in connection with a Principal
Prepayment in full or otherwise in excess of amounts required to be remitted to
the Master Servicer Collection Account. The Master Servicer shall be required to
pay all expenses incurred by it in connection with its activities hereunder and
shall not be entitled to reimbursement therefor except as provided in this
Agreement.

     Section 4.15 REO PROPERTY.

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

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

     (c) The Master Servicer and the Company or the applicable Servicer, upon
the final disposition of any REO Property, shall be entitled to reimbursement
for any related unreimbursed Advances and other unreimbursed advances as well as
any unpaid Servicing Fees from Liquidation

                                      -72-
<PAGE>

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

     (d) To the extent provided in 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
applicable Servicer as provided above shall be deposited in the Protected
Account on or prior to the Determination Date in the month following receipt
thereof and be remitted by wire transfer in immediately available funds to the
Master Servicer for deposit into the related Master Servicer Collection Account
on the next succeeding Remittance Date.

     Section 4.16 ANNUAL OFFICER'S CERTIFICATE AS TO COMPLIANCE.

     (a) The Master Servicer shall deliver to the Trustee and the Rating
Agencies on or before May 31 of each year, commencing on May 31, 2003, an
Officer's Certificate, certifying that with respect to the period ending
December 31 of the prior year: (i) such Servicing Officer has reviewed the
activities of such Master Servicer during the preceding calendar year or portion
thereof and its performance under this Agreement, (ii) to the best of such
Servicing Officer's knowledge, based on such review, such Master Servicer has
performed and fulfilled its duties, responsibilities and obligations under this
Agreement in all material respects throughout such year, or, if there has been a
default in the fulfillment of any such duties, responsibilities or obligations,
specifying each such default known to such Servicing Officer and the nature and
status thereof, (iii) nothing has come to the attention of such Servicing
Officer to lead such Servicing Officer to believe that 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 such Servicing Officer and
the nature and status thereof.

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

     Section 4.17 ANNUAL INDEPENDENT ACCOUNTANT'S SERVICING REPORT. If the
Master Servicer has, during the course of any fiscal year, directly serviced any
of the Mortgage Loans, then the Master Servicer at its expense shall cause a
nationally recognized firm of independent certified public accountants to

before May 31 of each year, commencing on May 31, 2003 to the effect that, with
respect to the most recently ended fiscal year, such firm has examined certain
records and documents relating to the Master Servicer's performance of its

agreements in material respects similar to this Agreement and to each other and
that, on the basis of such examination conducted substantially in compliance
with the audit program for mortgages serviced for Freddie Mac or the Uniform
Single Attestation Program for Mortgage

                                      -73-

been conducted in compliance with this Agreement, or that such examination has
disclosed no material items of noncompliance except for (i) such exceptions as
such firm believes to be immaterial, (ii) such other exceptions as are set forth
in such statement and (iii) such exceptions that the Uniform Single Attestation
Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by
Freddie Mac requires it to report. Copies of such statements shall be provided
to any Certificateholder upon request by the Master Servicer, or by the Trustee
at the expense of the Master Servicer if the Master Servicer shall fail to
provide such copies. If such report discloses exceptions that are material, the
Master Servicer shall advise the Trustee whether such exceptions have been or
are susceptible of cure, and will take prompt action to do so.

     Section 4.18 REPORTS FILED WITH SECURITIES AND EXCHANGE COMMISSION. Within
15 days after each Distribution Date, the Securities Administrator shall, in
accordance with industry standards, file with the Commission via the Electronic
Data Gathering and Retrieval System ("EDGAR"), a Form 8-K with a copy of the

Certificateholders for such Distribution Date as an exhibit thereto. Prior to
January 30, 2003, the Securities Administrator shall, in accordance with
industry standards and only if instructed by the Seller, file a Form 15
Suspension Notice with respect to the Trust Fund, if applicable. Prior to March
30, 2003, the Securities Administrator shall file a Form 10-K, in substance
conforming to industry standards, with respect to the Trust Fund. The Seller
hereby grants to the Securities Administrator a limited power of attorney to
execute and file each such document on behalf of the Seller. Such power of
attorney shall continue until either the earlier of (i) receipt by the
Securities Administrator from the Seller of written termination of such power of
attorney and (ii) the termination of the Trust Fund. The Seller agrees to
promptly furnish to the Securities Administrator, from time to time upon
request, such further information, reports and financial statements within its
control related to this Agreement and the Mortgage Loans as the Securities
Administrator reasonably deems appropriate to prepare and file all necessary
reports with the Commission. The Securities Administrator shall have no
responsibility to file any items other than those specified in this Section
4.18; provided, however, the Securities Administrator will cooperate with the
Seller in connection with any additional filings with respect to the Trust Fund
as the Seller deems necessary under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"). Copies of all reports filed by the Securities
Administrator under the Exchange Act shall be sent to: the Seller c/o Bear,
Stearns & Co. Inc., Attn: Managing Director-Analysis and Control, One Metrotech
Center North, Brooklyn, New York 11202- 3859. Fees and expenses incurred by the

     Section 4.21 OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.

                                      -74-
<PAGE>

     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.

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

                                    ACCOUNTS

     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, 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 or REMIC II, the Company may, (A) amend the related Mortgage Note
to reduce the Net Mortgage Rate applicable thereto, provided that such reduced
Net Mortgage Rate shall in no event be lower than 7.00% 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 "Bank One, National Association, in trust for
registered holders of Bear Stearns Asset Backed Securities, Inc., Asset- Backed
Certificates Series 2002-AC2". 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

payment charges or assumption fees, if collected, need not be remitted by the
Company. In the event that the Company shall remit any amount not required to be
remitted and not otherwise subject to withdrawal pursuant to Section 5.02, it
may at any time withdraw or direct the institution maintaining the Protected
Account, to withdraw such amount from the Protected Account, any provision
herein to the contrary notwithstanding. Such withdrawal or direction may be
accomplished by delivering written notice thereof to the institution maintaining
the Protected Account, that describes the amounts deposited in error in the

all withdrawals made pursuant to this Section. All funds deposited in the
Protected Account (other than any Prepayment Charges deposited therein) shall be
held in trust for the Certificateholders until withdrawn in accordance with
Section 5.02. Notwithstanding anything to the contrary contained herein, in the
event that the Company assigns the servicing obligations with respect to all or
a portion of the EMC Mortgage Loans to a successor pursuant to Section 8.05(b)
hereof, such successor may be entitled to retain the Prepayment Charges with
respect to any EMC Mortgage Loans serviced by such successor and collected
directly from the related Mortgagor and may not be required to remit any such

hereof.

the funds in the Protected Account, in the manner directed by the Company, in
Permitted Investments which shall mature not later than the Remittance Date and
shall not be sold or disposed of prior to its maturity. All such Permitted
Investments shall be made in the name of the Trustee, for the benefit of the
Certificateholders. All income and gain net of any losses realized from any such
investment shall be for the benefit of the Company as servicing compensation and
shall be remitted to it monthly as provided herein. The amount of any losses
incurred in the Protected Account in respect of any such investments shall be
deposited by the Company into the Protected Account, out of the Company's own
funds.

          (d) The Company shall give at least 30 days advance notice to the
Trustee, the Seller, the Master Servicer, each Rating Agency and the Depositor
of any proposed change of location of the Protected Account prior to any change
thereof.

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

required or permitted by this Agreement. To the extent provided in this
Agreement or the related Servicing Agreement, the Protected Account shall be
held in a Designated Depository Institution and segregated on the books of such
institution in the name of the Trustee for the benefit of Certificateholders.

          (b) To the extent provided in this Agreement or the related Servicing
Agreement, amounts on deposit in a Protected Account may be invested in
Permitted Investments in the name of the Trustee for the benefit of
Certificateholders and, except as provided in the preceding paragraph, not

Company or the related Servicer shall withdraw or shall cause to be withdrawn
from its Protected Account and shall immediately deposit or cause to be

following collections and payments (other than with respect to principal of or
interest on the Mortgage Loans due on or before the Cut-off Date):

          (b) The Master Servicer shall keep and maintain separate accounting,
on a Mortgage Loan by Mortgage Loan basis, for the purpose of accounting for any
reimbursement from the Distribution Account pursuant to subclauses (i) through
(vi), inclusive, and (viii) or with respect to any such amounts which would have
been covered by such subclauses had the amounts not been retained by the Master
Servicer without being deposited in the Distribution Account under Section 5.06.

          (c) On each Distribution Date, the Trustee shall distribute the
Available Funds in the Distribution Account to the holders of the Certificates
in accordance with Section 6.04.

                           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 Master Servicing Fee and
Servicing Fee for such Mortgage Loan except to the extent the Master Servicer
determines any such Advance to be nonrecoverable from Liquidation Proceeds,

                                      -87-

Insurance Proceeds or future payments on the Mortgage Loan for which such
Advance was made. Subject to the foregoing, the 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 a 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 the related Servicer under the
applicable 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 the Master Servicing Fee for
such Distribution Date, in the event the Company or the related Servicer fails
to do so.

     Section 6.03 REMIC DISTRIBUTIONS.

          On each Distribution Date the Securities Administrator, as agent for
the Trustee, shall allocate distributions to the REMIC I Regular Interests in
accordance with Section 6.06 hereof.

     Section 6.04 DISTRIBUTIONS.

          (a) On each Distribution Date, an amount equal to the Available Funds

     Certificates), on a pro rata basis, the Accrued Certificate Interest on
     each such Class for such Distribution Date;

          SECOND, to the Senior Certificates (other than the Class PO
     Certificates), on a pro rata basis, any Accrued Certificate Interest
     thereon remaining undistributed from previous Distribution Dates, to the

          THIRD, to the Class R-1 and Class R-2 Certificates, in reduction of

     Funds, until the Certificate Principal Balance of each such Class has been
     reduced to zero;

          FOURTH, to the Class A-9 Certificates, in reduction of the Certificate
     Principal Balance thereof, the Lockout Percentage of the Class A-9
     Certificates pro rata share (based on the Certificate Principal Balance
     thereof relative to the Stated Principal Balance of the Non- Discount
     Mortgage Loans) of the remaining Senior Optimal Principal Amount for such
     Distribution Date after distributions pursuant to priority THIRD above;

          FIFTH, concurrently (i) to the Class A-1 Certificates, Class A-2
     Certificates, Class A-3 Certificates and Class A-7 Certificates, in
     reduction of the Certificate Principal Balance thereof of each such Class,
     85.71428602058% of the Senior Optimal Principal Amount for such
     Distribution Date remaining after distributions pursuant to clause FOURTH
     above, in the following order, first, to the Class A-1 Certificates until
     the Certificate Principal Balance thereof has been reduced to zero, then,
     to the Class A-2 Certificates and the Class A-3 Certificates, pro rata,
     until the Certificate Principal Balances of such Classes have been reduced
     to zero, and then, to the Class A-7 Certificates until the Certificate
     Principal Balance thereof has been reduced to zero, and (ii) to the Class
     A-5 Certificates, 14.28571397942% of the Senior Optimal Principal Amount
     for such Distribution Date remaining after distributions pursuant to
     priority FOURTH above, until the Certificate Principal Balance thereof has
     been reduced to zero;

          SIXTH, to the Class A-9 Certificates, any Senior Optimal Principal
     Amount for such Distribution Date remaining after distributions pursuant to
     priority FIFTH above, until the Certificate Principal Balance thereof has
     been reduced to zero;

          SEVENTH, to the Class PO Certificates, the Class PO Certificate
     Principal Distribution Amount for such Distribution Date, to the extent of
     remaining Available Funds, until the Certificate Principal Balance thereof
     has been reduced to zero; and

          EIGHTH, to the Class PO Certificates, the Class PO Certificate
     Deferred Amount, provided, that (i) on any Distribution Date, distributions
     pursuant to this priority EIGHTH shall not exceed the excess, if any, of
     (x) Available Funds remaining after giving effect to distributions pursuant
     to priority FIRST through SEVENTH above over (y) the sum of the amount of
     Accrued Certificate Interest for such Distribution Date and Accrued
     Certificate Interest remaining undistributed from previous Distribution
     Dates on all Classes of Subordinated Certificates then outstanding, (ii)
     such distributions shall not reduce the Certificate Principal Balance of
     the Class PO Certificates and (iii) no distribution will be made in respect
     of the Class PO Certificate Deferred Amount on or after the Cross-over
     Date.

                                      -89-
<PAGE>

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

          (b) If, after distributions have been made pursuant to priorities
FIRST through SECOND of clause (a)(i) above on any Distribution Date, the
remaining Available Funds are less than the sum of the Senior Optimal Principal
Amount and the Class PO Certificate Distribution Amount such amounts shall be
proportionately reduced, and such remaining available funds will be distributed
to the Class A-1, Class A-2, Class A-3, Class A-5, Class A-7, Class A-9 and
Class PO Certificates on the basis of such reduced amount. Notwithstanding any
reduction in principal distributable to the Class PO Certificates pursuant to
this paragraph, the Certificate Principal Balance of the Class PO Certificates
shall be reduced not only by principal so distributed but also by the difference
between (i) principal distributable to the Class PO Certificates in accordance
with the priority SEVENTH under clause (a)(i) above and (ii) principal actually
distributed to the Class PO Certificates after giving effect to this paragraph
(such difference, the "Class PO Certificate Cash Shortfall"). The Class PO
Certificate Cash Shortfall with respect to any Distribution Date will be added
to the Class PO Certificate Deferred Amount.

          (c) On each Distribution Date, any available funds remaining after
payment of interest and principal to the Classes of Certificates entitled
thereto, as described above, will be distributed to the Class R-2 Certificates.

          (d) Subject to Section 11.02 hereof respecting the final distribution,
on each Distribution Date the Trustee shall make distributions to each
Certificateholder of record on the preceding Record Date either by wire transfer
in immediately available funds to the account of such holder at a bank or other
entity having appropriate facilities therefor, if (i) such Holder has so
notified the Trustee at least 5 Business Days prior to the related Record Date
and (ii) such Holder shall hold Regular Certificates with aggregate principal
denominations of not less than $1,000,000 or evidencing a Percentage Interest
aggregating 10% or more with respect to such Class or, if not, by check mailed
by first class mail to such Certificateholder at the address of such holder
appearing in the Certificate Register. Notwithstanding the foregoing, but
subject to Section 11.02 hereof respecting the final distribution, distributions
with respect to Certificates registered in the name of a Depository shall be
made to such Depository in immediately available funds.

          (e) On or before 5:00 p.m. Eastern time on the fifth Business Day
immediately preceding each Distribution Date, the Master Servicer shall deliver
a report to the Securities Administrator in the form of a computer readable
magnetic tape (or by such other means as the Master Servicer and the Securities
Administrator may agree from time to time) containing such data and information,
as agreed to by the Master Servicer and the Securities Administrator such as to
permit the Securities Administrator to prepare the Monthly Statement to
Certificateholders and to direct the Trustee in writing to make the required
distributions for the related Distribution Date (the

                                      -90-
<PAGE>

"Remittance Report"). The Securities Administrator shall deliver a Remittance
Report to the Trustee on or before 5:00 p.m. Eastern time on the Business Day
immediately preceding each Distribution Date.

     Section 6.04A ALLOCATION OF REALIZED LOSSES.

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

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

          (i) The PO Percentage of any such Realized Loss on a Discount Mortgage
     Loan and any Class PO Certificate Cash Shortfall shall be allocated to the
     Class PO Certificates; and

          (ii) The Non-PO Percentage of any such Realized Loss on a Mortgage
     Loan shall be allocated as follows:

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

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

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

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

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

               sixth, to the Class B-1 Certificates until the Certificate
               Principal Balance thereof has been reduced to zero; and

               seventh, to the Classes of Senior Certificates (other than the
               Class A-4, Class A-6, Class A-8, Class A-10, Class X1 and Class
               PO Certificates), pro rata, in accordance with their Certificate
               Principal Balances;

          (c) Notwithstanding the foregoing clause (b), no such allocation of
any Realized Loss shall be made on a Distribution Date to any Class of
Certificates to the extent that such allocation would result in the reduction of
the aggregate Certificate Principal Balances of all the Certificates as of such
Distribution Date, after giving effect to all distributions and prior
allocations of Realized

                                      -91-
<PAGE>

Losses on such date, to an amount less than the aggregate Stated Principal
Balance of all of the Mortgage Loans as of the first day of the month of such
Distribution Date (such limitation, the "Loss Allocation Limitation").

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

     (e) Realized Losses shall be allocated on the Distribution Date in the
month following the month in which such loss was incurred and, in the case of
the principal portion thereof, after giving effect to distributions made on such
Distribution Date, except that the aggregate amount of Realized Losses to be
allocated to the Class PO Certificates on any Distribution Date through the
Cross-Over Date will be taken into account in determining distributions in
respect of the Class PO Certificate Deferred Amount for such Distribution Date.

     (f) On each Distribution Date, the Securities Administrator shall determine
the Applied Realized Loss Amount. Any such Applied Realized Loss Amount shall
effect a corresponding reduction in the Certificate Principal Balance of (i) if
prior to the Cross-Over Date, the Subordinated Certificates, in the reverse
order of their numerical Class designations and (ii) from and after the
Cross-Over Date, the Senior Certificates (other than the Class A-4, Class A-6,
Class A-8, Class A-10 and Class X1 Certificates) which reduction shall occur on
such Distribution Date after giving effect to distributions made on such
Distribution Date.

     (g) On each Distribution Date, on or prior to the Cross-Over Date the
Securities Administrator shall determine the Class PO Certificate Deferred
Payment Writedown Amount with respect to the Class PO Certificates, if any. Any
such Class PO Certificate Deferred Payment Writedown Amount with respect to the
Class PO Certificates shall effect a corresponding reduction in the Certificate
Principal Balance of the Subordinated Certificates in the reverse order of their
numerical Class designations.

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

          Regular Interests for such Distribution Date, plus any Uncertificated
          Accrued Interest thereon remaining unpaid from any previous
          Distribution Date; and

          (ii) In accordance with the priority set forth in Section 6.06(c), an
          amount equal to the sum of the amounts in respect of principal
          distributable on the Class A-1, Class A-2, Class A-3, Class A-5, Class
          A-7, Class A-9, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5,
          Class B-6, Class PO and Class R-2 Certificates under Section 6.04, as
          allocated thereto.

          (c) The amount described in Section 6.06(b)(ii) shall be deemed
distributed to (i) REMIC I Regular Interest LTI-A1, (ii) REMIC I Regular
Interest LTI-A2, (iii) REMIC I Regular Interest LTI-A3, (iv) REMIC I Regular
Interest LTI-A5, (v) REMIC I Regular Interest LTI-A7, (vi) REMIC I Regular
Interest LTI-A-9, (vii) REMIC I Regular Interest LTI-B, (viii) REMIC I Regular
Interest LTI-PO and (ix) REMIC I Regular Interest LTI-R2 with the amount to be
distributed allocated among such interests in accordance with the priority and
amount assigned to (i) the Class A-1 Certificates, (ii) the Class A-2
Certificates, (iii) the Class A-3 Certificates, (iv) the Class A-5 Certificates,
(v) the Class A-7 Certificates, (vi) the Class A-9 Certificates, (vii) the Class
B Certificates, (viii) the Class PO Certificates and (ix) the Class R-2
Certificates, respectively, under Section 4.01 until the Uncertificated
Principal Balance of each such interest is reduced to zero.

          (d) the REMIC I Regular Interest distribution amounts described in
Section 4.04(a)(ii) shall be deemed distributed by REMIC I to REMIC II in
accordance with the priority assigned to the REMIC II Certificates relative to
that assigned to the REMIC I Certificates under Section 4.01(b).

          (e) In determining from time to time the REMIC I Regular Interest
distribution amount for a particular REMIC I Regular Interest, Realized Losses
allocated to the Certificates under Section 6.04A shall be allocated to the
REMIC I Regular Interests in the same amounts and priorities as allocated to the
Certificates with the corresponding numerical designation in 6.06(c) above.

          (f) On each Distribution Date the Trustee shall be deemed to
distribute from REMIC II, in the priority set forth in Sections 6.04, to the
Certificates the amounts distributable thereon, from the REMIC I Regular
Interests deemed to have been received by REMIC II from REMIC I under this
Section 6.06.

          (g) Notwithstanding the deemed distributions on the REMIC I Regular
Interests described in this Section 6.06, distributions of funds from the
Distribution Account shall be made only in accordance with Section 6.04.

          For purposes of calculating the amount of Uncertificated Accrued
Interest for the REMIC I Regular Interests for any Distribution Date, the
aggregate amount of any Net Interest Shortfalls incurred in respect of the
Mortgage Loans for any Distribution Date shall be allocated in the same manner
and extent as such amounts are allocated to the Certificates with the same
numerical and alphabetical designation.

          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 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.

                                      -99-

<PAGE>

          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 Subordinated 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 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 Subordinated 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
Subordinate Certificate desiring to effect such 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
the Trustee, the Master Servicer and the Securities Administrator shall have
received either (i) 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, an Opinion of
Counsel satisfactory to the Trustee, the Master Servicer and the Securities
Administrator to the effect that the purchase or holding of such ERISA
Restricted

                                     -100-
<PAGE>

Certificate will not result in any prohibited transactions under ERISA or
Section 4975 of the Code and will not subject the Trustee, the Master Servicer
or the Securities Administrator to any obligation in addition to those expressly
undertaken in this Agreement, which Opinion of Counsel shall not be an expense
of the Trustee, the Master Servicer 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 to the Trustee, the Master Servicer and the Securities
Administrator of an Opinion of Counsel satisfactory to the Trustee, the Master
Servicer and the Securities Administrator 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, the Master Servicer
and the Securities Administrator 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.

          (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.

                                     -101-
<PAGE>

          (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 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, 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 the REMIC I and/or REMIC II, 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 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 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.

                                     -103-
<PAGE>

          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;

          (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

                                     -104-
<PAGE>

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 Trustee or 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 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 the Corporate Trust Office where
Certificates may be surrendered for registration of transfer or exchange. The
Trustee initially designates its Corporate Trust Office, as the office for such
purposes. The Trustee will give prompt written notice to the Certificateholders
of any change in such location of any such office or agency.

               THE DEPOSITOR, 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 or the Certificates (i)
related to the Master Servicer's failure to perform its duties in compliance
with this Agreement (except as any such loss, liability or expense shall be
otherwise reimbursable pursuant to this Agreement) or (ii) incurred by reason of
the Master Servicer's willful misfeasance, bad faith or gross negligence in the
performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder, provided, in each case, that with respect to
any such claim or legal action (or pending or threatened claim or legal action),
the Trustee shall have given the Master Servicer and the Seller written notice
thereof promptly after the Trustee shall have with respect to such claim or
legal action knowledge thereof. This indemnity shall survive the resignation or
removal of the Trustee, Master Servicer or the Securities Administrator and the
termination of this Agreement.

     (b) The 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

                                     -106-
<PAGE>

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 referred to in
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 Company and the
Master Servicer to indemnify the Indemnified Persons pursuant to Section 8.03:

     (a) None of 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 Custodian and any
director, officer, employee or agent of the Depositor, the Company, the Master
Servicer or the Custodian shall be indemnified by the Trust and held harmless
thereby against any loss, liability or expense (including reasonable legal fees
and disbursements of counsel) incurred on their part that may be sustained in
connection with, arising out of, or related to, any claim or legal action
(including any pending or threatened claim or legal action) relating to this
Agreement, the Certificates or any Servicing Agreement (except 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

                                     -107-
<PAGE>

applicable Servicing Agreement), other than (i) any such loss, liability or
expense related to the Depositor's, 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 Depositor's, 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) None of 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 Depositor, the
Company or 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 Depositor, the Company 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 any Servicer, 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 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 delivered to the Trustee. No such resignation by the Master
Servicer shall become effective until EMC or the Trustee or a successor to the
Master Servicer reasonably satisfactory to the Trustee shall have assumed the
responsibilities and obligations of the Master Servicer in accordance with
Section 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

                                     -108-
<PAGE>

good standing that has a net worth of not less than $10,000,000 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. 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. Any
determination permitting the resignation of the Servicer shall be evidenced by
an Opinion of Counsel to such effect 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 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.

     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
loans for Fannie Mae or Freddie Mac; (b) shall have a net worth of not less than
$10,000,000 (unless otherwise approved by each Rating Agency pursuant to clause
(ii) below); (c) shall be reasonably satisfactory to the Trustee (as evidenced
in a writing signed by the Trustee); and (d) shall execute and deliver to the
Trustee an agreement, in form and substance reasonably satisfactory to the
Trustee, which contains an assumption by such Person of the due and punctual
performance and observance of each covenant and condition to be performed or
observed by it as master servicer under this Agreement, any custodial agreement
from and after the effective date of such agreement; (ii) each Rating Agency
shall be given prior written notice of the identity of the proposed successor to
the Master Servicer and each Rating Agency's rating of the Certificates in
effect immediately prior to such assignment, sale and delegation will not be
downgraded, qualified or withdrawn as a result of such assignment, sale and
delegation, as evidenced by a letter to such effect delivered to the Master
Servicer and the Trustee; (iii) the Master Servicer assigning and selling the
master servicing shall deliver to the Trustee an Officer's Certificate and an
Opinion of Counsel, each stating that all conditions precedent to such action
under this Agreement have been completed and such action is permitted by and
complies with the terms of this Agreement; and (iv) in the event the Master
Servicer is terminated

                                     -109-
<PAGE>

without cause by EMC, EMC shall pay the terminated Master Servicer a termination
fee equal to 0.25% of the aggregate Scheduled Principal Balance of the Mortgage
Loans at the time the master servicing of the Mortgage Loans is transferred to
the successor Master Servicer. No such assignment or delegation shall affect any
liability of the Master Servicer arising prior to the effective date thereof.

events:

          (i) any failure by the Master Servicer to remit to the Trustee any
     payment, including any Advance, required to be made pursuant to this

     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

     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

          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 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 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"). 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, 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 X. The Master Servicer agrees to cooperate with the Trustee in
effecting the termination of the Master Servicer'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 5.04, 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 and applicable law including, if applicable, the obligation to make
Advances pursuant to Article VI except as otherwise provided herein. Effective
on the date of such notice of termination, as compensation therefor, the Trustee
shall be entitled to all fees, costs and expenses relating to the Mortgage Loans
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 any 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 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 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 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 known to 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 known to the Trustee,
unless such Event of Default shall have been cured, notice of each such Event of
Default hereunder known to the Trustee. The Holders of Certificates evidencing
Fractional Undivided Interests aggregating not less than 51% of the Trust Fund
may, on behalf of all Certificateholders, waive any default by the Master
Servicer in the performance of its obligations hereunder and the consequences
thereof, except a default in the making of or the causing to be made any
required distribution on the Certificates. Upon any such waiver of a past
default, such default shall be deemed to cease to exist, and any Event of
Default arising therefrom shall be deemed to have been timely remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereon except to the extent
expressly so waived. The Trustee shall give notice of any such waiver to the
Rating Agencies.

     Section 9.04 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 which continues
unremedied for a period of one Business Day; 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
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,

                                     -114-
<PAGE>

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

     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 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 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

                                     -117-
<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 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

                                     -118-
<PAGE>

obligations of the Master Servicer or the Company hereunder or any Servicer
under the applicable 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 any
     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

                                     -119-
<PAGE>

     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

                                     -120-
<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. 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 reimbursement obligation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust.

          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

     Section 10.08 RESIGNATION AND REMOVAL OF TRUSTEE AND SECURITIES
                   ADMINISTRATOR.

          The Trustee and the Securities Administrator may at any time resign
and be discharged from the Trust hereby created by giving written notice thereof
to the 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 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

                                     -122-

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 9.06 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 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

                                     -123-
<PAGE>

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 9.06 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.

          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

                                     -124-
<PAGE>

     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 (and
the Securities Administrator is hereby appointed to act as agent) 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

                                     -125-
<PAGE>

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 last 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, 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

                                     -126-
<PAGE>

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 or REMIC II 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 or REMIC II 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 or REMIC II, 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 to all other Certificateholders in the following order of
priority: first, to the Class B-6 Certificates, second, to the Class B-5
Certificates, third, to the Class B-4 Certificates, fourth to the Class B-3
Certificates, fifth to the Class B-2 Certificates, sixth to the Class B-1
Certificates and seventh, to the Senior 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

                                     -127-
<PAGE>

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.

                                   TERMINATION

     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 upon the
earlier of (a) the purchase by the Company of all of the Mortgage Loans (and REO
Properties) remaining in the Trust Fund at a price equal to the sum of (i) 100%
of the Stated Principal Balance of each Mortgage Loan (other than in respect of
REO 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 Company and the Securities
Administrator and (iv) unreimbursed out-of pocket costs of the Company, the
related Servicer 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 applicable. In no event shall the trusts
created hereby continue beyond the earlier of (i) the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the
late Ambassador of the United States to the Court of St. James, 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) above shall be conditioned upon the Stated Principal Balance of
all of the Mortgage Loans in the Trust Fund, at the time of any such repurchase,
aggregating ten percent or less of the aggregate Cut- off Date Principal Balance
of all of the Mortgage Loans.

     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
Corporate Trust Office of the Trustee. If the Company elects to terminate the
Trust Fund pursuant to Section 11.01, at least 20 days prior to the date notice
is to be

                                     -129-
<PAGE>

mailed to the Certificateholders, the Company shall notify the Master Servicer,
the Depositor, the Securities Administrator, the Trustee and the Securities
Administrator of the date the Company intends to terminate the Trust Fund. The
Company shall remit the Mortgage Loan Repurchase Price to the Master Servicer on
the Business Day prior to the Distribution Date for such Optional Termination by
the Company.

          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 shall promptly release to the Company or the related Servicer, as
applicable the Mortgage Files for the Mortgage Loans and any documents 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 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.

                                     -130-
<PAGE>

          (a) Upon exercise by the Company 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, at the expense of
the Company, 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 Company 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 each of REMIC I and REMIC II's Tax Return pursuant to Treasury
Regulation Section 1.860F-1. The Company 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 obtained at the expense of the
Company;

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

                            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, 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 and REMIC II as a REMIC under the Code or to avoid or
minimize the risk of the imposition of any tax on any of REMIC I or REMIC II
pursuant to the Code that would be a claim against any of REMIC I or REMIC II at
any time prior to the final redemption of the Certificates, provided that the
Trustee has been provided an Opinion of Counsel, which opinion shall be an
expense of the party requesting such opinion but in any case shall not be an
expense of the Trustee or the Securities Administrator, 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's or REMIC II's REMIC election to fail to qualify 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, which opinion shall be an expense of the party
requesting such amendment but in any case shall not be an expense of the Trustee
or the Securities Administrator, to the effect that such

                                     -132-
<PAGE>

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 or REMIC II or the Certificateholders or cause REMIC I's or REMIC II's
REMIC election to fail to qualify 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

THEREOF.

                                     -133-
<PAGE>

          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 12.08 LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

          The death or incapacity of any Certificateholder shall not operate to

herein) or in any manner otherwise control the operation and management of the
Trust Fund, or the obligations of the parties hereto, nor shall anything herein
set forth or contained in the terms of the Certificates be construed so as to
constitute the Certificateholders from time to time as partners or members of an
association; nor shall any Certificateholder be under any liability to any third
party by reason of any action taken by the parties to this Agreement pursuant to
any provision hereof.

          No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or

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

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, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans were
sold by EMC Mortgage Corporation

                                      A-1-2

<PAGE>

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

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
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 2002-AC2

     evidencing a fractional undivided interest in the distributions
     allocable to the Class A-2 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, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans were
sold by EMC Mortgage Corporation

<PAGE>

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

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
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

reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced hereby, and the rights,

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-2-4

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.

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.

                            ASSET-BACKED CERTIFICATE
                                 SERIES 2002-AC2

     evidencing a fractional undivided interest in the distributions
     allocable to the Class A-3 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, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans were
sold by EMC Mortgage Corporation

                                      A-3-2

<PAGE>

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

          Interest on this Certificate will accrue during the period commencing
on the prior Distribution Date (or, in the case of the First Distribution Date
specified above, the Closing Date) and ending on the day prior to the current
Distribution Date on the Certificate Principal Balance hereof at a per annum
rate equal to the Pass-Through Rate set forth above. The Trustee will distribute
on the 25th day of each month, or, if such 25th day is not a Business Day, the
immediately following Business Day (each, a "Distribution Date"), commencing on
the First Distribution Date, 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-3-4

<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.

Neither this Certificate nor the underlying Mortgage Loans are guaranteed or

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

calendar month preceding the month of such Distribution Date, an amount equal to
the product of the Percentage Interest evidenced by this Certificate and the
amount of interest required to be distributed to the Holders of Certificates of
the same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in April 2032.

          Distributions on this Certificate will be made by the Trustee by check

amendment thereof and the modification of the rights and obligations of the
Depositor and the rights of the Certificateholders under the Agreement from time

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

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.

                                 SERIES 2002-AC2

    evidencing a fractional undivided interest in the distributions
    allocable to the Class A-5 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, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans were
sold by EMC Mortgage Corporation

                                      A-5-2

<PAGE>

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

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
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 the 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-5-4

<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.

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

                                 SERIES 2002-AC2

    evidencing a fractional undivided interest in the distributions
    allocable to the Class A-7 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, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans were
sold by EMC Mortgage Corporation

                                      A-7-2

<PAGE>

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

          Interest on this Certificate will accrue during the period commencing
on the prior Distribution Date (or, in the case of the First Distribution Date
specified above, the Closing Date) and ending on the day prior to the current
Distribution Date on the Certificate Principal Balance hereof at a per annum
rate equal to the Pass-Through Rate set forth above. The Trustee will distribute
on the 25th day of each month, or, if such 25th day is not a Business Day, the
immediately following Business Day (each, a "Distribution Date"), commencing on
the First Distribution Date, 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 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

                                      A-7-4

<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.

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-8
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

                                      A-8-4

<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.

                            ASSET-BACKED CERTIFICATE
                                 SERIES 2002-AC2

    evidencing a fractional undivided interest in the distributions
    allocable to the Class A-9 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, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans were
sold by EMC Mortgage Corporation

                                      A-9-2

<PAGE>

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

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
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 the 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

                                      A-9-4

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.

mortgage loans secured by one- to four- family residences, units in planned unit

EMC Mortgage Corporation as seller and company, Wells Fargo Bank Minnesota,
National Association, as Master Servicer and securities administrator (the

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
Notional 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
preceding the month of such Distribution Date, an amount equal to the product of
the Percentage Interest evidenced by this Certificate and the amount of interest
required to be distributed to the Holders of Certificates of the same Class as
this Certificate. The Assumed Final Distribution Date is the Distribution Date
in April 2032.

          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-10
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

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

                                     A-10-4

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.

                            ASSET-BACKED CERTIFICATE
                                 SERIES 2002-AC2

    evidencing a fractional undivided interest in the distributions
    allocable to the Class PO 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, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans were
sold by EMC Mortgage Corporation

                                     A-12-2

<PAGE>

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

          The Trustee will distribute on the 25th day of each month, or, if such
25th day is not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last Day (or if such last day is not a Business Day, the
Business Day immediately preceding such last day) of the calendar month
preceding the month of such Distribution Date, an amount equal to the product of
the Percentage Interest evidenced by this Certificate and the amount of
principal 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.

                                     A-12-3

<PAGE>

          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 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 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.

    evidencing a fractional undivided interest in the distributions
    allocable to the Class B-1 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, units in planned unit developments

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

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
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 and Class PO
Certificate Deferred Payment Writedown Amounts 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

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

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

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

                                 SERIES 2002-AC2

    evidencing a fractional undivided interest in the distributions
    allocable to the Class B-2 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, units in planned unit developments
and individual condominium units (collectively, the "Mortgage Loans") sold by
Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The Mortgage Loans were
sold by EMC Mortgage Corporation

                                     A-14-2

<PAGE>

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

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
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 and Class PO
Certificate Deferred Payment Writedown Amounts 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.

          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

                                     A-14-4

<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.

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

Neither this Certificate nor the underlying Mortgage Loans are guaranteed or

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 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

                            ASSET-BACKED CERTIFICATE
                                 SERIES 2002-AC2

    evidencing a fractional undivided interest in the distributions
    allocable to the Class B-4 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 [Bear, Stearns Securities Corp.] 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, units in planned unit
developments and individual condominium units (collectively, the "Mortgage
Loans") sold by Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The
Mortgage Loans were sold by EMC Mortgage

                                     A-16-3

<PAGE>

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

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
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 and Class PO
Certificate Deferred Payment Writedown Amounts allocable hereto.

          No transfer of this Certificate shall be made unless the transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and an effective registration or
qualification under applicable state securities laws, or is made in a
transaction that does not require such registration or qualification. In the
event that such a transfer 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 Exhibits E,

                                     A-16-4

<PAGE>

and 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 B-4 Certificate will be made unless the
Trustee and the Securities Administrator have received either (i) an opinion of
counsel acceptable to and in form and substance satisfactory to the Trustee, the
Securities Administrator and the Master Servicer with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
of a Class B-4 Certificate will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan.

          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

                                     A-16-5

<PAGE>

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 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 2002-AC2

    evidencing a fractional undivided interest in the distributions
    allocable to the Class B-5 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 [Bear, Stearns Securities Corp.] 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, units in planned unit
developments and individual condominium units (collectively, the "Mortgage
Loans") sold by Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The
Mortgage Loans were sold by EMC Mortgage

<PAGE>

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

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
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 and Class PO
Certificate Deferred Payment Amounts allocable hereto.

          No transfer of this Certificate shall be made unless the transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and an effective registration or
qualification under applicable state securities laws, or is made in a
transaction that does not require such registration or qualification. In the
event that such a transfer 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

                                     A-17-4

<PAGE>

Holder's prospective transferee, substantially in the forms attached to the
Agreement as Exhibits E, and 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 B-5 Certificate will be made unless the
Trustee and the Securities Administrator have received either (i) an opinion of
counsel acceptable to and in form and substance satisfactory to the Trustee, the
Securities Administrator and the Master Servicer with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
of a Class B-5 Certificate will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan.

          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

                                     A-17-5

<PAGE>

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 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.

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 and Class PO
Certificate Deferred Payment Writedown Amounts allocable hereto.

          No transfer of this Certificate shall be made unless the transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and an effective registration or
qualification under applicable state securities laws, or is made in a
transaction that does not require such registration or qualification. In the
event that such a transfer 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 Exhibits E,

                                     A-18-4

<PAGE>

and 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 B-6 Certificate will be made unless the
Trustee and the Securities Administrator have received either (i) an opinion of
counsel acceptable to and in form and substance satisfactory to the Trustee, the
Securities Administrator and the Master Servicer with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
of a Class B-6 Certificate will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan.

          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

                                     A-18-5

<PAGE>

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 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 2002-AC2

   evidencing a fractional undivided interest in the distributions
   allocable to the Class R-1 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 [Bear, Stearns Securities Corp.] 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, units in planned unit
developments and individual condominium units (collectively, the "Mortgage
Loans") sold by Bear Stearns Asset Backed Securities, Inc. ("BSABS"). The
Mortgage Loans were sold by EMC Mortgage

                                     A-19-3

<PAGE>

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

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

          The Trustee will distribute on the 25th day of each month, or, if such
25th day is not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last 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 amounts required to be distributed to the Holders of Certificates of the
same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month following the latest scheduled maturity date of
any Mortgage Loan.

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

                                     A-19-4

<PAGE>

          No transfer of this Class R-1 Certificate will be made unless the
Trustee and the Securities Administrator have received either (i) an opinion of
counsel acceptable to and in form and substance satisfactory to the Trustee, the
Securities Administrator and the Master Servicer with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
of a Class R-1 Certificate will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan.

          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

                                     A-19-5

<PAGE>

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.

   evidencing a fractional undivided interest in the distributions
   allocable to the Class R-2 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 [Bear, Stearns Securities Corp.] 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, units in planned unit
developments and individual condominium units (collectively, the "Mortgage
Loans") sold by Bear Stearns Asset Backed Securities, Inc.("BSABS"). The
Mortgage Loans were sold by EMC Mortgage

                                     A-20-3

<PAGE>

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

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

          The Trustee will distribute on the 25th day of each month, or, if such
25th day is not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last 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 amounts required to be distributed to the Holders of Certificates of the
same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month following the latest scheduled maturity date of
any Mortgage Loan.

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

                                     A-20-4

<PAGE>

          No transfer of this Class R-2 Certificate will be made unless the
Trustee and the Securities Administrator have received either (i) an opinion of
counsel acceptable to and in form and substance satisfactory to the Trustee, the
Securities Administrator and the Master Servicer with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
of a Class R-2 Certificate will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan.

          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

                                     A-20-5

<PAGE>

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.

          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

          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

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

          THIS CUSTODIAL AGREEMENT (as amended and supplemented from time to

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

          WHEREAS, the Depositor, the Seller, the Master Servicer and the
Trustee have entered into a Pooling and Servicing Agreement, dated as of April
1, 2002, relating to the issuance of Bear Stearns Asset Backed Securities Trust
2002-AC2, Asset-Backed Certificates, Series 2002-AC2 (as in effect on the date
of this agreement, the "Original Pooling and Servicing Agreement," and as
amended and supplemented from time to time, the "Pooling and Servicing
Agreement'); and

          WHEREAS, the Custodian has agreed to act as agent for the Trustee for
the purposes of receiving and holding certain documents and other instruments
delivered by the Depositor, the Seller or the Master Servicer under the Pooling
and Servicing Agreement and the Servicers under their respective Servicing
Agreements, all upon the terms and conditions and subject to the limitations
hereinafter set forth;

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

                                   ARTICLE I.
                                   DEFINITIONS

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

<PAGE>

                                   ARTICLE II.
                          CUSTODY OF MORTGAGE DOCUMENTS

          Section 2.1. CUSTODIAN TO ACT AS AGENT: ACCEPTANCE OF MORTGAGE FILES.
The custodian, as the duly appointed agent of the Trustee for these purposes,
acknowledges (subject to any exceptions noted in the Initial Certification
referred to in Section 23(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 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
Trustee an Initial Certification in the form annexed hereto as Exhibit One
evidencing receipt (subject to any exceptions noted therein) of a Mortgage File
for each of the Mortgage Loans listed on the Schedule attached hereto (the
"Mortgage Loan Schedule").

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

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

<PAGE>

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

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

          Section 2.4. NOTIFICATION OF BREACHES OF REPRESENTATIONS AND
WARRANTIES. Upon discovery by the Custodian of a breach of any representation or
warranty made by the Seller 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 Seller, the related Servicer (if applicable)
and the Trustee.

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

          Upon the Custodian's receipt of a request for release (a "Request for
Release") substantially in the form of Exhibit H to the Pooling and Servicing
Agreement signed by a Servicing Officer of the Company or the related 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 related
Servicer, as applicable, the related Mortgage File. The Depositor shall deliver
to the Custodian and the Custodian agrees to accept the Mortgage Note and other
documents constituting the Mortgage File with respect to any 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, the Company or the related 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 related 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 related Servicer, as applicable. The Company
or the related Servicer, as applicable, shall cause each Mortgage File or any
document therein so released to be returned to the Custodian when the need

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

          Section 3.4. 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 with the consent of
the Master Servicer. In such event, the Trustee shall appoint, or petition a
court of competent jurisdiction to appoint, a successor Custodian hereunder. Any
successor Custodian shall be a depository institution subject to supervision or
examination by federal or state authority shall be able to satisfy the other
requirements contained in Section 3.7 and shall be unaffiliated with the
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

to this Agreement shall be valid or effective unless the same is in writing and
signed by all parties hereto, and neither the Depositor, the Company, the Master
Servicer nor the Trustee shall enter into any amendment hereof except as
permitted by the Pooling and Servicing Agreement. The Trustee shall give prompt
notice to the Custodian of any amendment or supplement to the Pooling and
Servicing Agreement and furnish the Custodian with written copies thereof.

          Section 4.3. GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED A CONTRACT

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.

herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall

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.

reasonable rules and regulations as may be adopted by the Owner for the safety,
care, and cleanliness of the premises or building and the preservation of good
order therein, including regulations relating to the use of any apparatus,

<PAGE>
             Owner leases the Premises to Tenant and Tenant leases the Premises
from Owner, together with the rights in common with others to use any portions
of the Property that are designated by Owner for the common use of tenants and
others.

           Tenant shall not use or store any hazardous material on or about the
premises or the building without Owners approval which approval will be at
Owners sole discretion. The term "hazardous material" means any hazardous or
toxic substance, material or waste which is or becomes regulated by any federal,
state or other local governmental authority including, without limitation, any
material or substance which is designated as a "hazardous substance". Tenant
shall also comply with all rules and regulations for use, storage, and disposal
of any hazardous material.

      6. CAPITALIZED COST Owner may choose to charge as additional rent any
amortized cost of capital improvements (as distinguished from replacement parts
or components installed in the ordinary course of business) made to the Property
which are: (1) performed primarily to reduce operating expense costs or
otherwise improve the operating efficiency of the Property; or (2) required to
comply with any Laws that become effective, or first interpreted to apply to the
Property, after the date of this lease. The cost of capital improvements shall
be amortized by Owner over the lesser of the Payback Period or five (5) years.

      7. OWNER SERVICES Owner and Tenant recognize that this Agreement to Lease
is a "Full Service Lease" (Gross Lease). Owner agrees to furnish Tenant with the
following services: (1) Water service for use in the lavatories on each floor on
which the Premises are located; (2) Heat and Air conditioning in season during
normal business hours, at such temperatures and in such amounts as are standard
for comparable building or as required by governmental authority. Tenant, upon
such advance notice as is reasonably required by Owner, shall have the right to
receive HVAC service during hours other than normal business hours. Owner will
have option to charge for the additional service; (3) Maintenance and repair of
the Property as described below; (4) Janitor service on Business Days. If
Tenant's use, floor covering or other improvements require special services in
excess of the standard service for the Building, Tenant shall pay the additional
cost attributable to the special services; (5) Elevator service; (6) Electricity
to the Premises for general office use, in accordance with and subject to the
terms and conditions as stated below; and (7) Such other services as Owner
reasonably determines are necessary or appropriate for the Property.

            Tenant's use of electrical service shall not exceed, either in
voltage, rated capacity, use beyond Normal Business Hours or overall load, that
which Owner deems to be standard for the Building. If Tenant requests permission
to consume excess electrical service, Owner may (1) grant consent; (2) refuse to
consent; or (3) may condition consent upon conditions that Owner reasonably
elects (including, without limitation, the installation of utility service
upgrades, meters, submeters, air handlers or cooling units), and the additional
usage (to the extent permitted by Law), installation and maintenance costs shall
be paid by Tenant. Owner shall have the right, to, but not obligated to,
separately meter electrical usage for the Premises and to measure electrical
usage by survey or other commonly accepted methods.

                                       2
<PAGE>
            All repairs necessary as a result of acts or negligence by Tenant,
its agents or invitees, to restore the premises, including public and common
areas of the building (such as lobby, stairs, landscaping, garage, corridors and
restroom) to a tenantable condition shall be done by or under the direction of
the Owner at the Tenant's expense.

            Neither personal property nor material belonging to Tenant shall be
placed, stored, or deposited in or around hallways, corridors, washrooms, or
other facilities used in common by all Tenants of the building. Such common
areas shall be under the sole jurisdiction and control of Owner.

      8. POSSESSION The Tenant agrees by taking possession of the premises that
such premises are tenantable and good condition and that the Tenant will take
good care of the premises and the same will not be changed without the written
consent of the Owner. Tenant shall not make any alterations, additions, or
improvements to anything attached to the building without prior written approval
from the Owner, which approval shall be at the Owners sole discretion (this
includes changes to locks, plumbing, cabling or wiring). All Tenant improvements
including moves, additions or changes shall be made at the Tenant's sole cost
and expense. The Owner may make any improvements that it deems necessary for the
preservation, safety, or improvement of the premises or building. All
alterations, additions, and improvements except fixtures installed by the Tenant
that are removable without damage to the building shall become the property of
the Owner. The Tenant shall, upon termination of this lease, surrender and
deliver up the premises to the Owner in as good of condition as when received by
the Tenant from the Owner, reasonable use and wear excepted.

      9. RIGHT OF ENTRY The Owner or its agent shall have the right to enter the
premises at all reasonable times for the purpose of inspection and for the
purpose of cleaning, repairing, or improving the premises or the building; and
when reasonably necessary for such purpose, may close entrances, doors,
corridors, or other facilities without liability to the Tenant. The Owner shall
have the right to enter the premises for the purpose of showing the premises to
prospective tenants for a period of one hundred eighty (180) days prior to the
expiration of the lease term.

      10. DESTRUCTION A total destruction of the building shall terminate this
lease. In the event of a partial destruction by fire or other casualty, the
Owner shall make repairs if they can be completed within sixty (60) days after
the occurrence of such damage. Until such repairs are completed, rent shall be
abated to the extent the premises are unusable by the Tenant. If repairs cannot
be made within sixty (60) days, the Owner may, at its option, make them within a
reasonable time. Notice of such election shall be given by written notice to the
Tenant within thirty (30) days after occurrence of the damage. Upon receipt of
such notice, Tenant may elect either to continue tenancy at an abated rate or to
cancel this lease. If such notice is not given, then either party may, by
written notice to the other, cancel this lease.

      11. SIGNAGE The Tenant shall not display any sign, notice, picture,
poster, or advertising matter whatsoever in or about the premises or building at
places visible from anywhere outside the premises without first obtaining the
Owner's written consent thereto.

      12. INDEMNIFICATION Tenant shall defend and indemnify Owner and save it
harmless from and against any and all liability, damages, costs, or expenses,
including attorneys'

                                       3
<PAGE>
fees, arising from negligent act or omission of Tenant, or of the officers,
contractors, licensees, agents, servants, employees, guests, invitees, or
visitors of Tenant in or about the premises, to any person or property,
occurring in or about the premises, provided that the foregoing provision shall
not be construed to make Tenant responsible for loss, damage, liability, or
expense resulting from injuries to third parties caused by the negligence of
Owner, or of any officer, contractor, licensees, agent, servant, employee,
guest, invitee, or visitor of Owner. Owner and Tenant each release the other
from responsibility for, and waive their entire claim of recovery for (1) any
loss or damage to the real or personal property of either located anywhere in
the building and including the building itself, arising out of or incident to
the occurrence of any of the perils which may be covered by the fire and
lightning insurance policy, with extended coverage endorsement, in common use in
the Seattle locality, and policies covering any loss by theft or water damage,
or (2) loss resulting from business interruption at premises or loss of rental
income from the building, arising out of or incident to the occurrence of any of
the perils which may be covered by the business interruption insurance policy
and by the loss of rental income insurance policy in common use in the Seattle
locality; to the extent that such risks under (1) and (2) are in fact covered by
insurance, each party shall cause its insurance carriers to consent to such
waiver and to waive all rights of subrogation against the other party.

      13. LIENS Tenant shall keep premises and the building free from any liens
or encumbrances arising out of any work performed by Tenant, materials furnished
by Tenant, or obligations incurred by Tenant. Upon the occurrence of any of the
following events, Owner may terminate this lease by giving Tenant notice of its
election to do so: (1) if Tenant files a voluntary petition in bankruptcy, or
for reorganization under the bankruptcy laws, or is adjudged bankrupt by a court
of competent jurisdiction; (2) if Tenant makes an assignment for the benefit of
creditors; or (3) if a receiver is appointed by a court of competent
jurisdiction for Tenant's business and it be established in the receivership
proceedings that Tenant is insolvent.

      14. DEFAULT Except for a default under the preceding paragraph for which
immediate right of termination is given to Owner, if Tenant fails to pay any
installment of rent within ten (10) days after written notice, or to perform any
other covenant under this lease within thirty (30) days after written notice
from Owner stating the nature of the default, Owner may cancel this lease and
reenter and take possession of the premises using all necessary force to do so;
provided, however, that if the nature of such default other than for nonpayment
of rent is such that the same cannot reasonably be cured within such thirty (30)
day period, Tenant shall not be deemed to be in default if Tenant shall within
such period commence such cure and thereafter diligently prosecute the same to
completion. Notwithstanding such retaking of possession by Owner, Tenant's
liability for the rent provided herein shall not be extinguished for the balance
of the term of this lease. Upon such reentry, Owner may elect either (1) to
terminate this lease, in which event Tenant shall immediately pay to Owner a sum
equal to that by which the then cash value of the total rent reserved under this
lease for the balance of the lease term exceeds the then reasonable rental value
of the premises for the balance of the lease term; or (2) without terminating
this lease, to relet all or any part of the premises as the agent of and for the
account of Tenant upon such terms and conditions as Owner may deem advisable, in
which event the rents received on such reletting shall be applied first to the
expenses of reletting and collection, including attorney's fees and real estate
commissions paid, and thereafter to pay of all sums due or to become due Owner
hereunder. If a sufficient sum shall not be thus realized to pay such

                                       4
<PAGE>
sums and other charges, Tenant shall pay Owner any deficiency monthly, and Owner
may bring an action therefor as such monthly deficiency shall arise.

            In the event of any such retaking of possession of the premises by
the Owner as herein provided, Tenant shall remove all personal property located
thereon and, upon failure to do so upon demand of Owner, Owner may remove and
store the same in any place selected by Owner, including but not limited to a
public warehouse, at the expense and risk of Tenant. If Tenant shall fail to pay
any sums due hereunder or the cost of storing any such property after it has
been stored for a period of thirty (30) days or more, Owner may sell any or all
of such property at public or private sale and shall apply the proceeds of such
sale first, to the cost of such sale; second, to the payment of the charges for
storage, if any; and third, to the payment of any other sums of money which may
be due from Tenant to Owner under the terms of this lease, and the balance, if
any, to Tenant.

            Tenant hereby waives all claims for damages that may be caused by
Owner's lawfully reentering and taking possession of the premises or lawfully
removing and storing the property of Tenant as herein provided, and will save
Owner harmless from loss, costs, or damages occasioned by Owner thereby, and no
such lawful reentry shall be considered or construed to be a forcible entry.

      15. ATTORNEYS' FEES If either the Tenant or the Owner shall commence any
legal action involving matters arising out of this lease, including suit by the
Owner for recovery of rent or possession of the premises, the losing party shall
pay the successful party attorneys' fees and cost reasonably incurred by the
successful party in connection with such suit or action.

      16. BREACH The acceptance of rent by the Owner shall not be a waiver of
any breach by the Tenant or any term or condition of this lease other than
failure of the Tenant to pay the particular rental so accepted, regardless of
Owner's knowledge of the breach, and the waiver of the Owner of any breach of
any condition herein shall not be deemed to be a waiver of such condition or any
subsequent breach thereof.

      17. ASSIGNMENT AND SUBLET Tenant shall not assign this lease or sublet the
premises or any part thereof without the prior written consent of the Owner,
which shall be at the sole discretion of the Owner.

      18. SUBORDINATION This lease shall be subordinated to any first mortgage
or deed of trust heretofore or hereafter placed upon the building to any and all
advances made or to be made thereunder and to all renewals, replacements, and
extensions thereof. The Tenant shall attorn to the purchaser of the building at
any foreclosure sale under such encumbrance, provided the rights of the Tenant
hereunder are recognized by such purchaser. Within fifteen (15) days of
presentation, the Tenant shall execute and deliver any subordination or
nondisturbance agreement and any estoppel certificate requested by the Owner
certifying, if such be true, that the Tenant is in occupancy, the nature of the
modification to the lease, if any, and the dates to which rents and other
charges have been paid.

      19. CONDEMNATION AND EMINENT DOMAIN If the whole of the premises, or if
such portion of either the premises or the facilities in the building as may be
required for the reasonable use of the premises, shall be taken by virtue of any
condemnation or eminent domain

                                       5
<PAGE>
proceeding, this lease shall automatically terminate as of the date of such
condemnation, or as of the date possession is taken by the condemning authority,
whichever is earlier. Current rent shall be apportioned as of the date of such
termination. In case of a taking of a part of the premises or a portion of the
facilities in the building not required for the reasonable use of the premises,
then this lease shall continue in full force and effect, and the rental shall be
equitably reduced based on the proportion by which the rentable area of the
premises is reduced, such rent reduction to be effective on the date of such
partial taking. No award for any partial or entire taking shall be apportioned,
and Tenant hereby assigns to the Owner any award which may be made in such
taking or condemnation together with any and all rights of Tenant now or
hereafter arising in or to the same or any part thereof; provided, however, that
nothing herein shall be deemed to give Owner any interest in or to require
Tenant to assign to Owner any award made to the Tenant for the taking of
personal property or fixtures belonging to Tenant, for the interruption of or
damage to Tenant's business, or for Tenant's moving expenses.

      14. NOTICE All notices required under this lease shall be in writing to
the addresses below stated or such other place as may be designated by either
party in writing.

      15. PREMISES NAME The Owner intends to use the name "PEMCO Financial
Center" for the building but reserves the right, in its sole discretion, to
change such name.

      16. PARKING Owner owns and operates parking facilities located on the
premises. Owner agrees to make parking available for customers in designated
area's of the building garage. In addition, Owner agrees to provide monthly
parking for Tenants employees as available at a monthly rate of eighty five
($85) dollars per parking stall. Said eighty five ($85) dollar rate may be
adjusted to a reasonable market rate at anytime at the sole discretion of the
Owner with reasonable notice to tenant.

      17. OWNER RIGHTS TO TERMINATE The Owner herein reserves the right to
terminate and cancel this Lease Agreement should it decide to develop or sell
said premises. If the Owner exercises this right, the Owner agrees to give the
Tenant one hundred twenty (120) days written notice of its intent to develop or
sell said premises.

      18. PREMISES SPACE ADJUSTMENT The Tenant and Owner herein understand that
from time to time it may be the desire to adjust the amount of square feet
(space) in said premises. The Tenant and Owner herein mutually agree to work
together to make any desired adjustments to the amount of space in said premises
providing that; 1) any request for additional space is subject to availability,
which shall be determined by the Owner; and 2) any request for a reduction of
space is subject to another user, acceptable to the Owner, assuming the
obligation of said space. Any adjustments will be in writing and all terms and
conditions of said Lease Agreement will remain in full force and effect.

      25. OWNER STAFF USEAGE Tenant recognizes that the Owner has staff within
its Real Estate Department that provides various building maintenance,
construction, space design, vendor contracting and other facility related
services. It is agreed that any services and/or work to be performed in or about
the premises shall go through and be performed by the Owners Real Estate
Department, unless mutually agreed otherwise. The Owners Real Estate Department
will act in the best interest of both the Tenant and Owner.
