                         POOLING AND SERVICING AGREEMENT

          Pooling and Servicing Agreement dated as of September 1, 2001, among
Structured Asset Mortgage Investments Inc., a Delaware corporation, as the
seller (the "Seller"), EMC Mortgage Corporation, a Delaware corporation ("EMC"),
as master servicer (the "Master Servicer"), and Wells Fargo Bank Minnesota,
National Association, a national banking association, as trustee (the
"Trustee").

                              PRELIMINARY STATEMENT

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

          As provided herein, the Trustee shall make an election for the assets
included in the Trust Fund to be treated for federal income tax purposes as a
REMIC ("REMIC I"). The Trustee shall also make an election for the certificates
issued by REMIC I, other than the Class R-1 Certificates, to be treated for
federal income tax purposes as a REMIC ("REMIC II"). For federal income tax
purposes, REMIC II shall be considered to have issued the Certificates, other
than the Class R-1 Certificates. On October 18, 2001 (the "Startup Day"), each
class of REMIC I Regular Certificates and each Class of Certificates except for
the Class R-1 and Class R-2 Certificates will be designated "regular interests"
in a REMIC. The Class R-1 and Class R-2 Certificates will be designated
"residual interests" in REMIC I and REMIC 2, respectively.

          The Mortgage Loans will consist of two Mortgage Loan Groups. The Group
1 Mortgage Loans and the Group 2 Mortgage Loans will have an aggregate Scheduled
Principal Balance as of the Cut-off Date, after deducting all Scheduled
Principal due or, in the case of the Simple Interest Loans in such Mortgage Loan
Group, the principal portion of all scheduled payments received, on or before
the Cut-off Date, of $67,065,251 and $15,137,663, respectively, or $82,202,914
for all of the Mortgage Loans. The initial principal amount of the Certificates
will not exceed such aggregate Scheduled Principal Balance.

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

                                   ARTICLE I

                                   Definitions

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

          ACCOUNT: The Certificate Account (including each subaccount thereof),
the Protected Accounts, the Servicing Accounts or the Accrued Interest Account
as the context may require.

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

          ACCRUED INTEREST ACCOUNT: The non-interest bearing trust account
created and maintained pursuant to Section 4.04 which shall be denominated
"Wells Fargo Bank Minnesota, National Association, as Trustee f/b/o holders of
Structured Asset Mortgage Investments Trust 2001-4 Mortgage Pass-Through
Certificates, Series 2001-4, Accrued Interest Account."

          ACCRUED INTEREST REIMBURSEMENT AMOUNT: With respect to the
Distribution Date in November 2001, an amount equal to $10,630.95, which is
equal to the sum of (a) the excess of (i) seventeen days of interest at the

Principal Amount of the Group 1 Senior Certificates, measured as of the close of
business on September 1, 2001, over (ii) seventeen days of interest at the
weighted average Net Rate of the Group 1 Mortgage Loans times the Current
Principal Amount of the Group 1 Senior Certificates measured as of the close of
business on October 1, 2001 and (b) the excess of (i) seventeen days of interest
at the weighted average Net Rate of the Group 2 Mortgage Loans times the Current
Principal Amount of the Group 2 Senior Certificates, measured as of the close of
business on September 1, 2001, over (ii) seventeen days of interest at the

Principal Amount of the Group 2 Senior Certificates measured as of the close of
business on October 1, 2001.

          ADVANCING DATE: The Business Day preceding the related Distribution

the management and policies of a Person, directly or indirectly, whether through

                    Date, the Current Principal Amount of any Class of
                    Subordinate Certificates for which the related Class

                         Mortgage Loan; and

               (vi) on the Distribution Date on which the Current Principal
          Amounts of the Senior Certificates have all been reduced to zero, 100%

          SUBORDINATE PERCENTAGE: On any Distribution Date with respect to each
Mortgage Loan Group, 100% minus the Senior Percentage for the related Senior
Certificate Group, initially 3.50% for each Mortgage Loan Group.

has been reduced to zero, the Subordinate Prepayment Percentage with respect to
that Mortgage Loan Group will equal 100%.

          SUBORDINATION TRIGGER: A test which will be met on any Distribution
Date, if an amount equal to 100% minus a fraction, the numerator of which is the
Current Principal Amount of the Senior Certificates and the denominator of which
is the aggregate Scheduled Principal Balance of the Mortgage Loans, in each
case, on such Distribution Date, equals or exceeds 7%.

and administration of certain Mortgage Loans as provided in Section 3.02.

          SUBSTITUTE MORTGAGE LOAN: A Mortgage Loan tendered to the Trustee
pursuant to Section 2.04, which will, in each case, in the opinion of the Master
Servicer, (i) have a Scheduled Principal Balance, after deduction of all
scheduled payments due in the month of substitution, not in excess of (and not
more than $10,000 less than) the Scheduled Principal Balance, after deduction of
all unpaid scheduled payments due as of the date of substitution, of the
Mortgage Loan for which it is being substituted, (ii) have a fixed Mortgage Rate
not less than (and not more than 1% greater than) the Mortgage Loan for which it
is being substituted, (iii) have a Net Rate not less than (and not more than 1%
greater than) the Net Rate of the Mortgage Loan for which it is being
substituted, (iv) have a remaining term to maturity not greater than (and not
more than one year less than) that of the Mortgage Loan for which it is being
substituted, (v) pay the same or a greater percentage of its Original Scheduled
Payment and (vi) comply with all representations and warranties set forth in
this Agreement as of the date of substitution. Notwithstanding the foregoing, if
the Mortgage Loan being substituted for is an FHA Loan or a VA Loan, the
Substitute Mortgage Loan shall also be an FHA Loan or a VA Loan, as the case may
be. In the event that one Mortgage Loan is substituted for more than one
Mortgage Loan, or more than one Mortgage Loan is substituted for one or more
Mortgage Loans, then the amount described in clause (i) will be determined on
the basis of aggregate Scheduled Principal Balances, the rates described in
clauses (ii) and (iii) with respect to Mortgage Loans being substituted for will
be determined on the basis of weighted average Mortgage Rates and Net Rates, as
the case may be, and the terms described in clause (iv) will be determined on
the basis of weighted average remaining terms to maturity. The opinion of the
Master Servicer shall be evidenced by an Officer's Certificate delivered to the
Trustee. For all purposes hereunder, a Substitute Mortgage Loan shall be in the
same Mortgage Loan Group as the Mortgage Loan for which it was substituted.

          TAX MATTERS PERSON: The Holder of the Class R-1 Certificate and the
Holder of the Class R-2 Certificate shall be the Tax Matters Person for REMIC I

successor in interest, or any successor trustee appointed as herein provided.

          UNINSURED CAUSE: Any cause of damage to a Mortgaged Property or REO
Property such that the complete restoration of such Mortgaged Property or REO
Property is not fully reimbursable by the hazard insurance policies required to
be maintained pursuant to Section 3.10, without regard to whether or not such
policy is maintained.

          VA: The United States Veterans Administration.

          VA LOANS: Any Mortgage Loan that is guaranteed by the VA.

such Mortgaged Property, in each case, at the time of origination of the related
Mortgage Loan or (b) in some cases, the Appraised Value of such Mortgaged
Property or (ii) the value thereof obtained by use of a BPO, using, if such BPO
provides a range of values, the highest value provided by such BPO.

          VOLUNTARY PRINCIPAL PREPAYMENT: With respect to any Distribution Date,
any Principal Prepayment received from the related Mortgagor on a Mortgage Loan.

         Conveyance of Mortgage Loans; Original Issuance of Certificates

          Section 2.01. CONVEYANCE OF MORTGAGE LOANS TO TRUSTEE. (a) The Seller
concurrently with the execution and delivery of this Agreement, sells, transfers
and assigns to the Trust without recourse all its right, title and interest in
and to (i) the Mortgage Loans identified in the Mortgage Loan Schedule,
including (A) in the case of all Mortgage Loans other than Simple Interest Loans
all interest and principal due after the Cut-off Date (i.e., excluding any
payments of principal and interest due on or prior to the Cut-off Date) and (B)
in the case of Simple Interest Loans, including all principal and interest due
after the Cut-Off Date and any payments of principal due on or prior to the
Cut-Off Date but received after the Cut-Off Date (i.e., excluding any interest
and principal due and received on or prior to the Cut-Off Date); (ii) the
Certificate Account and such assets as shall from time to time be credited or
are required by the terms of this Agreement to be credited to the Certificate
Account (excluding any income to the Trustee from Permitted Investments under
Subsection 4.02(d)), (iii) such assets relating to the Mortgage Loans as from
time to time may be held by the Master Servicer or a Sub-Servicer in Protected
Accounts (excluding any income to the Master Servicer or any Sub-Servicer from
Permitted Investments under Subsection 4.01(a)), (iv) any Servicing Accounts (to
the extent the mortgagee has a claim thereto and excluding any income to the
Master Servicer or Sub-Servicer or interest payable to Mortgagors pursuant to
applicable law), (v) any REO Property, (vi) the Required Insurance Policies and
any amounts paid or payable by the insurer under any Insurance Policy, FHA
insurance or VA guaranty (to the extent the mortgagee has a claim thereto),
(vii) rights under the Certificate Insurance Policy (for the benefit of the
Holders of the Senior Certificates only) and (viii) any proceeds of the
foregoing. Although it is the intent of the parties to this Agreement that the
conveyance of the Seller's right, title and interest in and to the Mortgage
Loans and other assets in the Trust Fund pursuant to this Agreement shall
constitute a purchase and sale and not a loan, in the event that such conveyance
is deemed to be a loan, it is the intent of the parties to this Agreement that
the Seller shall be deemed to have granted to the Trustee for the benefit of the
Certificateholders and the Certificate Insurer a first priority perfected
security interest in all of the Seller's right, title and interest in, to and
under the Mortgage Loans and other assets in the Trust Fund, and that this
Agreement shall constitute a security agreement under applicable law.

          (b) In connection with the above transfer and assignment, the Seller
hereby deposits with the Trustee, with respect to each Mortgage Loan, (i) the
original Mortgage Note, including any riders thereto, endorsed without recourse
to the order of the Trustee and showing to the extent available to the Seller an
unbroken chain of endorsements from the original payee thereof to the Person
endorsing it to the Trustee, (ii) the original Security Instrument, which shall
have been recorded (or if the original is not available, a copy), with evidence
of such recording indicated thereon, (iii) the assignment (either an original or
a copy, which may be in the form of a blanket assignment if permitted in the
jurisdiction in which the Mortgaged Property is located) to the Trustee of the
Security Instrument, in recordable form, with respect to each Mortgage Loan,
(iv) an original or a copy of all intervening assignments of the Security
Instrument, if any, to the extent available to the Seller, with evidence of
recording thereon, (v) the original policy of title insurance or mortgagee's
certificate of title insurance or commitment or binder for title insurance, if
available, or a copy thereof, (vi) any evidence of FHA Insurance or VA Guaranty,
if applicable, (vii) [intentionally omitted] and (viii) originals or copies of
all available assumption, modification or substitution agreements, if any;
PROVIDED, HOWEVER, that the assignment of the Security Instrument to the Trustee
will not be required to be submitted for recording with respect to any Mortgage
Loan if the Trustee and the Certificate Insurer shall have received an Opinion
of Counsel satisfactory to the Trustee and the Certificate Insurer stating that
in such counsel's opinion, the recordation of the assignment to the Trustee of
the Security Instrument securing a particular Mortgage Note is not necessary to
transfer to the assignee thereof all the benefits and security provided by the
Security Instrument as against the related assignor or any creditor of such
assignor, and the Security Instrument will continue to secure the Mortgage Note
to the same extent as if the Mortgage Note and Security Instrument had not been
assigned and delivered; and PROVIDED, FURTHER, HOWEVER, that in lieu of the
foregoing, the Seller may deliver the following documents, under the
circumstances set forth below: (x) if any Security Instrument, 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 to the Seller in time to permit their delivery as specified above, the
Seller may deliver a true copy thereof with a certification by EMC 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 314 Group 1 Mortgage Loans and 45 Group 2 Mortgage
Loans with an aggregate Scheduled Principal Balance of approximately $7,669,228
and $1,115,168, respectively, as of the Cut-Off Date and identified in the list
set forth on Exhibit I, the Seller may deliver a lost note affidavit and
indemnity and a copy of the original note, if available (which lost note
affidavit and indemnity may be in the form of a blanket affidavit and indemnity
covering all Lost Notes as of the Closing Date so long as individual affidavits
and indemnities are provided to the Trustee within 30 days thereafter); and
PROVIDED, FURTHER, HOWEVER, that in the case of Mortgage Loans which have been
prepaid in full after the Cut-Off Date and prior to the Closing Date, the
Seller, in lieu of delivering the above documents, may deliver to the Trustee 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 Certificate
Account on the Closing Date. In the case of the documents referred to in clause
(x) above, the Seller shall deliver such documents to the Trustee promptly after
they are received. The Master Servicer shall cause, at its expense, the Security
Instrument and intervening assignments, if any, and to the extent required in
accordance with the foregoing, the assignment of the Security Instrument to the
Trustee to be submitted for recording promptly after the Closing Date.

          Section 2.02. ACCEPTANCE OF MORTGAGE LOANS BY TRUSTEE. (a) The Trustee
acknowledges receipt of, subject to its further review and the exceptions it
notes pursuant to the procedures described below, the documents (or certified
copies thereof) delivered to it pursuant to Section 2.01 and declares that it
holds and will continue to hold those documents and any amendments, replacements
or supplements thereto and all other assets of the Trust Fund delivered to it as
Trustee in trust for the use and benefit of all present and future Holders of
the Certificates. On the Closing Date, the Trustee will deliver a certification
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. No
later than 90 days after the Closing Date (or, with respect to any Substitute
Mortgage Loan, within 5 Business Days after the receipt by the Trustee thereof),
the Trustee agrees, for the benefit of the Certificateholders and the
Certificate Insurer, to perform a limited review of the Mortgage Files delivered
to it and to execute and deliver, or cause to be executed and delivered, to the
Seller and EMC an Initial Certification substantially in the form annexed hereto
as Exhibit G. In conducting such review, the Trustee 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 it has received, as identified in
Exhibit B to this Agreement, as supplemented (PROVIDED, HOWEVER, that with
respect to those documents described in subclauses (b)(iv) and (b)(viii) of
Section 2.01, the Trustee's obligations shall extend only to documents actually
delivered pursuant to such subclauses). In performing any such review, the
Trustee 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 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
shall include such information in the exception report attached to Exhibit G.
EMC shall (or shall cause a prior transferor of the Mortgage Loan to) correct or
cure any such defect or shall deliver to the Trustee and the Certificate Insurer
an Opinion of Counsel to the effect that such defect does not materially or
adversely affect the interests of Certificateholders or the Certificate Insurer
in such Mortgage Loan within 90 days from the date of notice from the Trustee of
the defect and if EMC fails to correct or cure the defect or deliver such
opinion within such period, EMC will, subject to Section 2.04, within 90 days
from the Trustee's notification purchase such Mortgage Loan at the Repurchase
Price; PROVIDED, HOWEVER, that if such defect relates solely to the inability of
EMC to deliver the Security Instrument, 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, EMC shall not be required to purchase such Mortgage
Loan if EMC 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 (or with respect to
any Substitute Mortgage Loan becoming a part of the Trust after such 180 day
period, within 5 Business Days after the receipt by the Trustee thereof) , the
Trustee will review, for the benefit of the Certificateholders and the
Certificate Insurer, the Mortgage Files and will execute and deliver or cause to
be executed and delivered to the Seller and EMC, a Final Certification
substantially in the form annexed hereto as Exhibit H. In conducting such
review, the Trustee will ascertain whether (i) each document required to be
recorded has been returned from the recording office with evidence of recording
thereon and the Trustee has received either an original or a copy thereof, as
required in Section 2.01(b) (PROVIDED, HOWEVER, that with respect to those
documents described in subclauses (b)(iv) and (b)(viiii) of Section 2.01, the
Trustee's obligations shall extend only to documents actually delivered pursuant
to such subclauses); and (ii) an original title insurance policy (or if a master
title policy has been issued by the title insurer, a mortgagee's certificate of
title insurance), if available, or a copy thereof, whenever a title insurance
binder or commitment or other assurance of title was originally delivered to the
Trustee. If the Trustee finds any document discussed in clauses (i) or (ii) of
the preceding sentence 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 shall note such defect in the
exception report attached to the Final Certification. EMC shall correct or cure
any such defect or shall deliver to the Trustee and the Certificate Insurer an
Opinion of Counsel to the effect that such defect does not materially or
adversely affect the interests of Certificateholders or the Certificate Insurer
in such Mortgage Loan within 90 days from the date of notice from the Trustee of
the defect and if EMC is unable to correct or cure such defect within such
period or to deliver such opinion, EMC shall, subject to Section 2.04, within 90
days from the Trustee's notification purchase such Mortgage Loan at the
Repurchase Price; PROVIDED, HOWEVER, that if such defect relates solely to the
inability of EMC to deliver the Security Instrument, 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,
EMC shall not be required to purchase such Mortgage Loan, if EMC 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 EMC in
accordance with Subsections 2.02(a) or (b) above or by the Master Servicer in
accordance with Section 3.19 or by BSMCC in accordance with Section 3.20, EMC,
the Master Servicer or BSMCC, as applicable, shall remit the applicable
Repurchase Price to the Trustee for deposit in the appropriate subaccount of the
Certificate Account and shall provide written notice to the Trustee detailing
the components of the Repurchase Price, signed by a Servicing Officer. Upon
deposit of the Repurchase Price in the appropriate subaccount of the Certificate
Account and receipt of a properly completed Request for Release, the Trustee
shall release to EMC, the Master Servicer or BSMCC, as applicable, the related
Mortgage File and shall execute and deliver all instruments of transfer or
assignment, without recourse, furnished to it by such party, as are necessary to
vest in such party title to and rights under the Mortgage Loan. Such purchase
shall be deemed to have occurred on the date on which certification of the
deposit of the Repurchase Price in the Certificate Account was received by the
Trustee. The Trustee shall promptly notify the Rating Agency and the Certificate
Insurer of such repurchase. The obligation of EMC to repurchase any Mortgage
Loan pursuant to subclauses 2.02(a) or (b) as to which a defect in a constituent
document exists or of BSMCC to purchase Restricted Loans pursuant to Section
3.20 shall be the sole remedy respecting such defect or Restricted Loans
available to the Certificateholders or to the Trustee on their behalf.

          Section 2.03. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE MASTER
SERVICER. (a) EMC hereby represents and warrants to the Trustee and the
Certificate Insurer as of the Closing Date that:

               (i) It is a corporation duly organized, validly existing and in

          and in good standing under the laws of the state of its incorporation
          or any state of reincorporation and in good standing as a foreign
          corporation in each jurisdiction where such qualification is necessary
          (except, in the case of foreign corporation qualification both on the
          date hereof and in the future, where the failure so to qualify would
          not reasonably be expected to have a material adverse effect on the
          Master Servicer's ability to enter into this Agreement or to perform
          its obligations hereunder), and has the corporate power and authority
          to perform its obligations under this Agreement;

               (ii) The execution and delivery of this Agreement have been duly
          authorized by all requisite corporate action;

               (iii) This Agreement, assuming due authorization, execution, and
          delivery by the other parties hereto, will constitute its legal, valid
          and binding obligation, enforceable in accordance with its terms,
          except only as such enforcement may be limited by applicable Debtor
          Relief Laws and that certain equitable remedies may not be available
          regardless of whether enforcement is sought in equity or at law;

               (iv) Its execution and delivery of this Agreement and its
          performance and compliance with the terms of this Agreement will not
          (A) violate its certificate of incorporation or bylaws (B) to its
          knowledge, violate any law or regulation, or any administrative or
          judicial decree or order to which it is subject or (C) constitute a
          default (or an event which, with notice or lapse of time, or both,
          would constitute a default) under, or result in the breach of, any
          material contract, agreement or other instrument to which it is a
          party or which may be applicable to it or any of its assets;

               (v) To its best knowledge, after reasonable investigation, it is
          not in default with respect to any order or decree of any court or any
          order, regulation or demand of any federal, state, municipal or
          governmental agency, which default would reasonably be expected to
          have consequences that would materially and adversely affect its
          financial condition or operations or its performance hereunder;

               (vi) It does not believe, nor does it have any reason or cause to
          believe, that it cannot perform each and every covenant contained in
          this Agreement to be performed by it;

               (vii) The consummation of the transactions contemplated by this
          Agreement are in the ordinary course of its business;

               (viii) No litigation is pending or, to its best knowledge,
          threatened against it, which could be reasonably expected to
          materially and adversely affect its entering into this Agreement or
          performing its obligations under this Agreement or which would have a
          material adverse effect on its financial condition; and

               (ix) As to each Mortgage Loan, the Seller Contract is in full
          force and effect.

          Section 2.03A. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE
SELLER. (a) The Seller hereby makes the representations and warranties to the
Trustee and the Certificate Insurer set forth in Exhibit C hereto regarding the
Mortgage Loans. (b) If the Seller, the Master Servicer, the Certificate Insurer
or the Trustee discovers a breach of any of the representations and warranties
set forth in Exhibit C or Section 7 of the Seller Contract, and such breach
existed on the date the representation and warranty was made, which breach
materially and adversely affects the value of the interests of
Certificateholders, the Certificate Insurer or the Trustee in the related
Mortgage Loan, the party discovering the breach shall give prompt written notice
of the breach to the other parties and to EMC. EMC, within 90 days of its
discovery or receipt of notice that such breach has occurred (whichever occurs
earlier), shall (i) deliver to the Trustee an Opinion of Counsel to the effect
that such breach does not materially and adversely affect the interests of the
Certificateholders or the Trustee in such Mortgage Loan, (ii) cure the breach in
all material respects, or (iii) subject to Section 2.04, shall purchase the
Mortgage Loan or any property acquired with respect thereto from the Trustee;
PROVIDED, HOWEVER, that if there is a breach of any representation set forth in
Exhibit C and the Mortgage Loan or the related property acquired with respect
thereto has been sold, then EMC shall pay, in lieu of the Repurchase Price, any
excess of the Repurchase Price over the Net Liquidation Proceeds received upon
such sale. (If the Net Liquidation Proceeds exceed the Repurchase Price, any
excess shall be paid to EMC to the extent not required by law to be paid to the
borrower.) Any such purchase by EMC shall be made by remitting to the Trustee
for deposit in the appropriate subaccount of the Certificate Account an amount
equal to the Repurchase Price and the Trustee, upon receipt of the Repurchase
Price a properly completed Request for Release and of written notification of
such deposit by a Servicing Officer (which notification shall detail the
components of such Repurchase Price), shall release to EMC the related Mortgage
File and shall execute and deliver all instruments of transfer or assignment
furnished to it by EMC, without recourse, as are necessary to vest in EMC title
to and rights under the Mortgage Loan or any property acquired with respect
thereto. Such purchase shall be deemed to have occurred on the date on which
certification of the deposit of the Repurchase Price in the appropriate
subaccount of the Certificate Account was received by the Trustee. The Trustee
shall promptly notify the Rating Agency and the Certificate Insurer of such
repurchase. Enforcement of the obligation of EMC to purchase (or substitute a
Substitute Mortgage Loan for) any Mortgage Loan or any property acquired with
respect thereto (or pay the Repurchase Price as set forth in the above proviso)
as to which a breach has occurred and is continuing shall constitute the sole
remedy respecting such breach available to the Certificateholders or the Trustee
on their behalf.

          Section 2.04. SUBSTITUTION OF MORTGAGE LOANS. Notwithstanding anything
to the contrary in this Agreement, in lieu of purchasing a Mortgage Loan
pursuant to Sections 2.02 or 2.03A, EMC may, no later than the date by which
such purchase by EMC would otherwise be required, tender to the Trustee a
Substitute Mortgage Loan accompanied by an Officer's Certificate of EMC that
such Substitute Mortgage Loan conforms to the requirements set forth in the
definition of "Substitute Mortgage Loan"; PROVIDED, HOWEVER, that substitution
pursuant to this Section 2.04 in lieu of purchase shall not be permitted after
the termination of the two-year period beginning on the Startup Day. The Trustee
shall examine the Mortgage File for any Substitute Mortgage Loan in the manner
set forth in Section 2.02(a) and shall notify the Master Servicer in writing,
within five Business Days after receipt, whether or not the documents relating
to the Substitute Mortgage Loan satisfy the requirements of the third sentence
of Subsection 2.02(a). Within two Business Days after such notification, EMC
shall remit to the trustee for deposit in the appropriate subaccount of the
Certificate Account the amount, if any, by which the Scheduled Principal Balance
as of the next preceding Due Date of the Mortgage Loan for which substitution is
being made, after giving effect to Scheduled Principal due on such date, exceeds
the Scheduled Principal Balance as of such date of the Substitute Mortgage Loan,
after giving effect to Scheduled Principal due on such date, which amount shall
be treated for the purposes of this Agreement as if it were the payment by EMC
of the Repurchase Price for the purchase of a Mortgage Loan by EMC. After such
notification to EMC, and, if any such excess exists, upon receipt of such
deposit and of written notification thereof signed by a Servicing Officer, the
Trustee shall accept such Substitute Mortgage Loan, which shall thereafter be
deemed to be a Group 1 Mortgage Loan or a Group 2 Mortgage Loan, as applicable,
hereunder. In the event of such a substitution, accrued interest on the
Substitute Mortgage Loan for the month in which the substitution occurs and any
Principal Prepayments made thereon during such month shall be the property of
the Trust Fund and accrued interest for such month on the Mortgage Loan for
which the substitution is made and any Principal Prepayments made thereon during
such month shall be the property of EMC. The Scheduled Principal on a Substitute
Mortgage Loan due on the Due Date in the month of substitution shall be the
property of EMC and the Scheduled Principal on the Mortgage Loan for which the
substitution is made due on such Due Date shall be the property of the Trust
Fund. Upon acceptance of the Substitute Mortgage Loan and receipt of a properly
completed Request for Release, the Trustee shall release to EMC the related
Mortgage File related to any Mortgage Loan released pursuant to this Section
2.04 and shall execute and deliver all instruments of transfer or assignment,
without recourse, in form as provided to it as are necessary to vest in EMC
title to and rights under any Mortgage Loan released pursuant to this Section
2.04. EMC shall deliver the documents related to the Substitute Mortgage Loan in
accordance with the provisions of Subsections 2.01(b) and 2.02(b), with the date
of acceptance of the Substitute Mortgage Loan deemed to be the Closing Date for
purposes of the time periods set forth in those Subsections. The representations
and warranties set forth in Exhibit C shall be deemed to have been made by EMC
with respect to each Substitute Mortgage Loan as of the date of acceptance of
such Mortgage Loan by the Trustee. The Trustee shall amend the Mortgage Loan
Schedule to reflect such substitution and shall provide a copy of such amended
Mortgage Loan Schedule to the Master Servicer and the Rating Agency.

          Section 2.05. REPRESENTATIONS AND WARRANTIES OF THE TRUSTEE. The
Trustee hereby represents and warrants to the Seller, the Master Servicer and
the Certificate Insurer, as of the Closing Date (and in the case of paragraph
(v) below throughout the term of the Agreement), that:

               (i) The Trustee is a national banking association duly organized,
          validly existing and in good standing under the laws of the United
          States of America;

               (ii) Subject to the right of the Trustee to appoint a co-trustee
          or separate trustee under Section 9.11 hereof in order to meet the
          legal requirements of a particular jurisdiction, the Trustee has full
          power, authority and legal right to execute and deliver this Agreement
          and to perform its obligations under this Agreement and has taken all
          necessary corporate action to authorize the execution and delivery of
          the Certificates, and the execution, delivery and performance by it of
          this Agreement;

               (iii) To the best of the Trustee's knowledge, after reasonable
          investigation, the execution and delivery by the Trustee of this
          Agreement and the Certificates and the performance by the Trustee of
          its obligations under this Agreement will not violate any provision of
          the Trustee's Articles of Incorporation or By-Laws or any law or
          regulation governing the Trustee or any order, writ, judgment or
          decree of any court, arbitrator or governmental authority or agency
          applicable to the Trustee or any of its assets. To the best of the
          Trustee's knowledge, after reasonable investigation, such execution,
          delivery and performance will not require the authorization, consent
          or approval of, the giving of notice to, the filing or registration
          with, or the taking of any other action with respect to, any
          governmental authority or agency regulating the activities of a
          national banking association. To the best of the Trustee's knowledge,
          after reasonable investigation, such execution, delivery and
          performance will not conflict with, or result in a breach or violation
          of, any material indenture, mortgage, deed of trust, lease or other
          agreement or instrument to which the Trustee is a party or by which it
          or its properties is bound;

               (iv) This Agreement has been duly executed and delivered by the
          Trustee. This Agreement, when executed and delivered, will constitute
          the valid, legal and binding obligation of the Trustee, enforceable
          against the Trustee in accordance with its terms, except as the
          enforcement thereof may be limited by applicable Debtor Relief Laws
          and that certain equitable remedies may not be available regardless of
          whether enforcement is sought in equity or at law; and

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

          Section 2.06. ISSUANCE OF CERTIFICATES. The Trustee acknowledges the
assignment to it of the Mortgage Loans and the other assets comprising the Trust
Fund and, concurrently therewith, has signed, and countersigned and delivered to
the Seller, in exchange therefor, Certificates in such authorized denominations
representing such Fractional Undivided Interests as the Seller has requested.
The Trustee agrees that it will hold the Mortgage Loans and such other assets as
may be from time to time delivered to it segregated on the books of the Trustee
in trust for the benefit of the Certificateholders and the Certificate Insurer.

          Section 2.07. REPRESENTATIONS AND WARRANTIES CONCERNING THE SELLER.
The Seller hereby represents and warrants to the Trustee, the Certificate
Insurer and the Master Servicer as follows:

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

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

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

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

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

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

                                  ARTICLE III

                 Administration and Servicing of Mortgage Loans

          Section 3.01. MASTER SERVICER TO ASSURE SERVICING. (a) The Master
Servicer shall supervise, or take such actions as are necessary to ensure, the
servicing and administration of the Mortgage Loans and any REO Property in
accordance with this Agreement and its normal servicing practices (including
making any Servicing Advances), which generally conform to the standards of an
institution prudently servicing mortgage loans for its own account and shall
have full authority to do anything it reasonably deems appropriate or desirable
in connection with such servicing and administration. The Master Servicer may
perform its responsibilities relating to servicing through other agents or
independent contractors, but shall not thereby be released from any of its
responsibilities as hereinafter set forth. The authority of the Master Servicer,
in its capacity as master servicer, shall include, without limitation, the power
to (i) consult with and advise any Sub-Servicer regarding administration of a
related Mortgage Loan, (ii) approve any recommendation by a Sub-Servicer to
foreclose on a related Mortgage Loan, (iii) supervise the filing and collection
of insurance claims and take or cause to be taken such actions on behalf of the
insured person thereunder as shall be reasonably necessary to prevent the denial
of coverage thereunder, and (iv) effectuate foreclosure or other conversion of
the ownership of the Mortgaged Property securing a related Mortgage Loan,
including the employment of attorneys, the institution of legal proceedings, the
collection of deficiency judgments, the acceptance of compromise proposals, the
filing of claims under any Primary Mortgage Insurance Policy, where applicable,
and any other matter pertaining to a delinquent Mortgage Loan. The Master
Servicer shall also follow any applicable bankruptcy court, HUD, FHA or VA
requirements and/or regulations, where applicable, regarding the servicing of
the Mortgage Loans, including but not limited to any limitations on the ability
to institute foreclosure proceedings upon the occurrence of a default in the
payment of Monthly Payments, or the making of insurance or guaranty claims. The
Master Servicer will not foreclose on or sell or approve any recommendation to
foreclose on or sell any Mortgage Loan based solely on the delinquency status in
existence on the Closing Date. The authority of the Master Servicer shall
include, in addition, the power on behalf of the Certificateholders, the Trustee
or any of them to (i) execute and deliver customary consents or waivers and
other instruments and documents, (ii) consent to transfers of any related
Mortgaged Property and assumptions of the related Mortgage Notes and Security
Instruments (in the manner provided in this Agreement) and (iii) collect any
Insurance Proceeds and Liquidation Proceeds. Without limiting the generality of
the foregoing, the Master Servicer may, and is hereby authorized, and empowered
by the Trustee to, execute and deliver, on behalf of itself, the
Certificateholders, the Trustee, or any of them, any instruments of
satisfaction, cancellation, partial or full release, discharge and all other
comparable instruments, with respect to the related Mortgage Loans, the
Insurance Policies and the accounts related thereto, and the Mortgaged
Properties. The Master Servicer may exercise this power in its own name or in
the name of a Sub-Servicer.

          (b) Notwithstanding the provisions of Subsection 3.01(a), the Master
Servicer shall not take any action inconsistent with the interest of the
Trustee, the Certificate Insurer or the Certificateholders in the Mortgage Loans
or with the rights and interests of the Trustee, the Certificate Insurer or the
Certificateholders under this Agreement.

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

          Section 3.02. SUB-SERVICING AGREEMENTS BETWEEN MASTER SERVICER AND
SUB-SERVICERS. (a) The Master Servicer may enter into Sub-Servicing Agreements
with Sub-Servicers for the servicing and administration of the Mortgage Loans
and for the performance of any and all other activities of the Master Servicer
hereunder. Each Sub-Servicer shall be either (i) an institution the accounts of
which are insured by the FDIC or (ii) another entity that engages in the
business of originating or servicing mortgage loans, and in either case shall be
authorized to transact business in the state or states in which the related
Mortgaged Properties it is to service are situated, if and to the extent
required by applicable law to enable the Sub-Servicer to perform its obligations
hereunder and under the Sub-Servicing Agreement, and in either case shall be a
Fannie Mae or Freddie Mac approved mortgage servicer. Any Sub-Servicing
Agreement entered into by the Master Servicer shall include the provision that
such Agreement may be immediately terminated (x) with cause and without any
termination fee by any Master Servicer hereunder other than EMC or (y) without
cause in which case the Master Servicer that entered into such Sub-Servicing
Agreement shall be responsible for any termination fee or penalty resulting
therefrom. In addition, any Sub-Servicing Agreement shall provide for servicing
of the Mortgage Loans consistent with the terms of this Agreement. With, so long
as the Senior Certificates are outstanding or any amounts are owed to the
Certificate Insurer, and the Certificate Insurer is not in default under the
Certificate Insurance Policy, the consent of the Certificate Insurer in its sole
discretion, the Master Servicer and the Sub-Servicers may enter into
Sub-Servicing Agreements and make amendments to the Sub-Servicing Agreements or
enter into different forms of Sub-Servicing Agreements; PROVIDED, HOWEVER, that
any such amendments or different forms shall be consistent with and not violate
the provisions of this Agreement.

          (b) As part of its servicing activities hereunder, the Master
Servicer, for the benefit of the Trustee, the Certificateholders and the
Certificate Insurer shall enforce the obligations of each Sub-Servicer under the
related Sub-Servicing Agreement. Such enforcement, including, without
limitation, the legal prosecution of claims, termination of Sub-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, but shall be reimbursed therefor only (i) from a general
recovery resulting from such enforcement only to the extent, if any, that such
recovery exceeds all amounts due in respect of the related Mortgage Loans or
(ii) from a specific recovery of costs, expenses or attorneys' fees against the
party against whom such enforcement is directed.

          Section 3.03. SUCCESSOR SUB-SERVICERS. The Master Servicer shall be
entitled to terminate any Sub-Servicing Agreement that may exist in accordance
with the terms and conditions of such Sub-Servicing Agreement and without any
limitation by virtue of this Agreement; PROVIDED, HOWEVER, that upon
termination, the Master Servicer shall either act as servicer of the related
Mortgage Loan or enter into an appropriate contract with a successor
Sub-Servicer pursuant to which such successor Sub-Servicer will be bound by all
relevant terms of the related Sub-Servicing Agreement pertaining to the
servicing of such Mortgage Loan.

          Section 3.04. LIABILITY OF THE MASTER SERVICER. (a) Notwithstanding
any Sub-Servicing Agreement, any of the provisions of this Agreement relating to
agreements or arrangements between the Master Servicer and a Sub-Servicer or
reference to actions taken through a Sub-Servicer or otherwise, the Master
Servicer shall under all circumstances remain obligated and primarily liable for
the servicing and administering of the Mortgage Loans and any REO Property in
accordance with this Agreement. The obligations and liability of the Master
Servicer shall not be diminished by virtue of Sub-Servicing Agreements or by
virtue of indemnification of the Master Servicer by any Sub-Servicer, or any
other Person. The obligations and liability of the Master Servicer shall remain
of the same nature and under the same terms and conditions as if the Master
Servicer alone were servicing and administering the related Mortgage Loans. The
Master Servicer shall, however, be entitled to enter into indemnification
agreements with any Sub-Servicer or other Person and nothing in this Agreement
shall be deemed to limit or modify such indemnification. For the purposes of
this Agreement, the Master Servicer shall be deemed to have received any payment
on a Mortgage Loan on the date the Sub-Servicer received such payment; PROVIDED,
however, that this sentence shall not apply to the Trustee acting as the Master
Servicer; PROVIDED, FURTHER, HOWEVER, that the foregoing provision shall not
affect the obligations of the Master Servicer if it is also the Trustee to
advance amounts which are not Nonrecoverable Advances.

          (b) Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such and not as an originator shall be deemed to be between
the Sub-Servicer and the Master Servicer alone, and the Trustee and
Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to the Sub-Servicer
except as set forth in Section 3.05.

          Section 3.05. ASSUMPTION OR TERMINATION OF SUB-SERVICING AGREEMENTS BY
TRUSTEE. (a) If the Trustee or its designee shall assume the master servicing
obligations of the Master Servicer in accordance with Section 8.02, the Trustee,
to the extent necessary to permit the Trustee to carry out the provisions of
Section 8.02 with respect to the Mortgage Loans, shall succeed to all of the
rights and obligations of the Master Servicer under each of the Sub-Servicing
Agreements. In such event, the Trustee or its designee as the successor master
servicer shall be deemed to have assumed all of the Master Servicer's rights and
obligations therein and to have replaced the Master Servicer as a party to such
Sub-Servicing Agreements to the same extent as if such Sub-Servicing Agreements
had been assigned to the Trustee or its designee as a successor master servicer,
except that the Trustee or its designee as a successor master servicer shall not
be deemed to have assumed any obligations or liabilities of the Master Servicer
arising prior to such assumption and the Master Servicer shall not thereby be
relieved of any liability or obligations under such Sub-Servicing Agreements.

          (b) In the event that the Trustee or its designee as successor master
servicer for the Trustee assumes the servicing obligations of the Master
Servicer under Section 8.02, upon the reasonable request of the Trustee or such
designee as successor master servicer, the Master Servicer shall at its own
expense deliver to the Trustee, or at its written request to such designee,
photocopies of all documents and records, electronic or otherwise, relating to
the Sub-Servicing Agreements and the related Mortgage Loans or REO Property then
being serviced and an accounting of amounts collected and held by it, if any,
and will otherwise cooperate and use its reasonable best efforts to effect the
orderly and efficient transfer of the Sub-Servicing Agreements, or
responsibilities hereunder to the Trustee, or at its written request to such
designee as successor master servicer.

          Section 3.06. COLLECTION OF MORTGAGE LOAN PAYMENTS. (a) The Master
Servicer will make remittances itself or will coordinate and monitor remittances
by Sub-Servicers to the Trustee with respect to the Mortgage Loans in accordance
with this Agreement.

          (b) The Master Servicer shall make its reasonable best efforts to
collect or cause to be collected all payments required under the terms and
provisions of the Mortgage Loans and shall follow, and use its best efforts to
cause Sub-Servicers to follow, collection procedures comparable to the
collection procedures of prudent mortgage lenders servicing mortgage loans for
their own account to the extent such procedures shall be consistent with this
Agreement. Consistent with the foregoing and subject to the provisions of
Section 3.06(d), the Master Servicer may in its discretion (i) waive or permit
to be waived any late payment charge, prepayment charge, assumption fee, or any
penalty interest in connection with the prepayment of a Mortgage Loan, (ii)
amend a Forbearance Plan or Bankruptcy Plan to enable the Mortgagor to satisfy
its obligations under the related Mortgage Loan and (iii) suspend or reduce or
permit to be suspended or reduced regular monthly payments for a period of up to
six months, or arrange or permit an arrangement with any Mortgagor for a
scheduled liquidation of delinquencies and with respect to Mortgage Loans which
have defaulted or as to which default is reasonably foreseeable, take such other
action, including, consistent with Sections 3.06(c) and 3.06(d), forgiving a
portion of the Scheduled Principal Balance thereof. In the event the Master
Servicer shall consent to the deferment of the due dates for payments due on a
Mortgage Note, the Master Servicer shall nonetheless make a Monthly Advance or
shall cause the related Sub-Servicer to make an advance (to the same extent as
if such installment were due, owing and delinquent and had not been deferred)
through liquidation of the Mortgaged Property; PROVIDED, HOWEVER, that the
obligation of the Master Servicer to make a Monthly Advance shall apply only to
the extent that the Master Servicer believes, in good faith, that such advances
are not Nonrecoverable Advances.

          (c) Notwithstanding anything in this Agreement to the contrary, the
Master Servicer may not make any advances of amounts coming due in the future
with respect to a Mortgage Loan and the Master Servicer shall not permit (i) any
modification with respect to any Mortgage Loan that would change the Mortgage
Rate, reduce or increase the principal balance (except for reductions resulting
from actual payments of principal) or change the final maturity date on such
Mortgage Loan (other than, with respect to FHA Loans or VA Loans, as may be
required by the FHA, HUD or the VA, as applicable, in connection with servicing
regulations for such Mortgage Loans) or (ii) any modification, waiver or
amendment of any term of any Mortgage Loan that would both (A) effect an
exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or
final, temporary or proposed Treasury regulations promulgated thereunder) and
(B) cause REMIC I or REMIC II to fail to qualify as a REMIC under the Code or
the imposition of any tax on "prohibited transactions" or "contributions after
the startup date" under the REMIC Provisions.

          (d) Notwithstanding the foregoing, if the Mortgagor is in default with
respect to the Mortgage Loan or such default is reasonably foreseeable, the
Master Servicer may, in its discretion, modify certain terms of the related
Mortgage Loan. Such modifications may include (i) a reduction in the Mortgage
Rate of a Mortgage Loan (but in no event to lower than 7.5%), (ii) a recasting
of the amortization schedule (based on a 30-year term) and/or an extension of
the scheduled date of final payment on such Mortgage Loan (but in no event
beyond the Assumed Final Distribution Date) and (iii) an increase or reduction
in the Scheduled Principal Balance of such Mortgage Loan. In addition, the
Master Servicer may in its discretion (i) waive or permit to be waived any late
payment charge or prepayment charge, assumption fee or any penalty interest in
connection with the prepayment of a Mortgage Loan and (ii) suspend or reduce or
permit to be suspended or reduced regular monthly payments for a period of up to
six months or arrange or permit an arrangement with a Mortgagor for a schedule
for the liquidation of delinquencies if, in the good faith judgment of the
Master Servicer, such action would minimize the losses that might otherwise be
experienced with respect to a Mortgage Loan, or in the event that a payment
default with respect to a Mortgage Loan is reasonably foreseeable by the Master
Servicer. In the event the Master Servicer shall consent to the deferment of due
dates for payments due on a Mortgage Note, the Master Servicer shall nonetheless
continue to make advances as required (to the same extent as if such installment
were due, owing and delinquent and had not been deferred) through liquidation of
the Mortgaged Property, but the Master Servicer shall make such advances only to
the extent that the Master Servicer believes, in good faith, that such advances
are recoverable from future payments on any Mortgage Loan.

          (e) Within five Business Days after the Master Servicer has determined
that all amounts which it expects to recover from or on account of a Mortgage
Loan have been recovered and that no further Liquidation Proceeds will be
received in connection therewith, the Master Servicer shall provide to the
Trustee a certificate of a Servicing Officer that such Mortgage Loan became a
Liquidated Mortgage Loan as of the date of such determination.

          Section 3.07. COLLECTION OF TAXES, ASSESSMENTS AND SIMILAR ITEMS;
SERVICING ACCOUNTS. (a) The Master Servicer shall establish and maintain or
cause the Sub-Servicers to establish and maintain, in addition to the Protected
Accounts, one or more Servicing Accounts. The Master Servicer or a Sub-Servicer
will deposit and retain therein all otherwise unapplied collections from the
Mortgagors, including amounts collected for the payment of taxes, assessments,
insurance premiums, or comparable items as agent of the Mortgagors.

          (b) The deposits in the Servicing Accounts shall be held in a
Designated Depository Institution in an account designated as a "Mortgage Loan
Servicing Account," held in trust by the Master Servicer or a Sub-Servicer as a
custodial account for borrowers and for the Master Servicer (and its successors
and assigns) acting on its own behalf and for the Master Servicer as agent for
holders of various pass-through securities and other interests in mortgage loans
sold by it; and agent for various mortgagors, as their interests may appear or
under such other designation as may be permitted by a Sub-Servicing Agreement.
The amount at any time credited to a Servicing Account must be fully insured by
the FDIC, or, to the extent that such deposits exceed the limits of such
insurance, such excess must be (i) transferred to another fully insured account
in another Designated Depository Institution or (ii) if permitted by applicable
law, invested in Permitted Investments held in trust by the Master Servicer or a
Sub-Servicer as described above and maturing, or be subject to redemption or
withdrawal, no later than the date on which such funds are required to be
withdrawn, and in no event later than 45 days after the date of investment. The
Master Servicer may, or may permit a Sub-Servicer to, establish Servicing
Accounts not conforming to the foregoing requirements to the extent that such
Servicing Accounts are Rating Agency Eligible Accounts. Withdrawals of amounts
from the Servicing Accounts may be made only to effect timely payment of taxes,
assessments, insurance premiums, or comparable items, to transfer previously
unapplied collections to a Protected Account, to reimburse the Master Servicer
or a Sub-Servicer for any advances made with respect to such items, to refund to
any Mortgagors any sums as may be determined to be overages, to pay interest, if
required, to Mortgagors on balances in the Servicing Accounts or to clear and
terminate the Servicing Accounts at or any time after the termination of this
Agreement in accordance with Section 10.01.

          Section 3.08. ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION
REGARDING THE MORTGAGE LOANS. The Master Servicer shall provide, and shall cause
any Sub-Servicer to provide, to the Trustee, the Certificate Insurer and the
Seller access to the records and documentation regarding the related Mortgage
Loans and REO Property and the servicing thereof and to the Certificateholders,
the FDIC, and the supervisory agents and examiners of the FDIC (to which the
Trustee shall also provide) access to the documentation regarding the related
Mortgage Loans required by applicable regulations, such access being afforded
without charge but only upon reasonable prior written request and during normal
business hours at the offices of the Master Servicer, the Sub-Servicers or the
Trustee that are designated by these entities; PROVIDED, HOWEVER, that, unless
otherwise required by law, the Trustee, the Master Servicer or the Sub-Servicer
shall not be required to provide access to such records and documentation if the
provision thereof would violate the legal right to privacy of any Mortgagor
PROVIDED, further, HOWEVER, that the Trustee, the Certificate Insurer and the
Seller shall coordinate their requests for such access so as not to impose an
unreasonable burden on, or cause an interruption of, the business of the Master
Servicer or any Sub-Servicer. The Master Servicer, the Sub-Servicers and the
Trustee shall allow representatives of the above entities to photocopy any of
the documentation and shall provide equipment for that purpose at a charge that
covers their own actual out-of-pocket costs.

          Section 3.09. MAINTENANCE OF PRIMARY MORTGAGE INSURANCE POLICIES;
COLLECTION THEREUNDER. The Master Servicer shall, or shall cause the related
Sub-Servicer to, exercise its best reasonable efforts to maintain and keep in
full force and effect each Primary Mortgage Insurance Policy by a Qualified
Insurer, or other insurer satisfactory to the Rating Agency, with respect to
each conventional Mortgage Loan as to which as of the Cut-off Date such a
Primary Mortgage Insurance Policy was in effect (or, in the case of a Substitute
Mortgage Loan, the date of substitution) to the level of each such Primary
Mortgage Insurance Policy as in effect on the Cut-Off Date. The Master Servicer
shall, or shall cause the related Sub-Servicer to, effect the timely payment of
the premium on each Primary Mortgage Insurance Policy. The Master Servicer and
the related Sub-Servicer shall have the power to substitute for any Primary
Mortgage Insurance Policy another substantially equivalent policy issued by
another Qualified Insurer; PROVIDED THAT such substitution is subject to the
condition, to be evidenced by a writing from the Rating Agency, that it would
not cause the ratings on the Certificates to be downgraded or withdrawn.

          Section 3.10. MAINTENANCE OF HAZARD INSURANCE AND FIDELITY COVERAGE.
(a) The Master Servicer shall maintain and keep, or cause each Sub-Servicer to
maintain and keep, with respect to each Mortgage Loan and each REO Property, in
full force and effect hazard insurance (fire insurance with extended coverage)
equal to at least the lesser of the Outstanding Principal Balance of the
Mortgage Loan or the current replacement cost of the Mortgaged Property, and
containing a standard mortgagee clause; PROVIDED, HOWEVER, that the amount of
hazard insurance may not be less than the amount necessary to prevent loss due
to the application of any co-insurance provision of the related policy. Unless
applicable state law requires a higher deductible, the deductible on such hazard
insurance policy may be $5,000 or 1% of the applicable amount of coverage,
whichever is less. In the case of a condominium unit or a unit in a planned unit
development, the required hazard insurance shall take the form of a multiperil
policy covering the entire condominium project or planned unit development, in
an amount equal to at least 100% of the insurable value based on replacement
cost.

          (b) Any amounts collected by the Master Servicer or a Sub-Servicer
under any such hazard insurance policy (other than amounts to be applied to the
restoration or repair of the Mortgaged Property or amounts released to the
Mortgagor in accordance with the Master Servicer's or a Sub-Servicer's normal
servicing procedures, the terms of the Mortgage Note, the Security Instrument or
applicable law) shall be deposited initially in a Protected Account, for
transmittal to the appropriate subaccount of the Certificate Account, subject to
withdrawal pursuant to Section 4.03.

          (c) Any cost incurred by a Master Servicer or a Sub-Servicer in
maintaining any such hazard insurance policy shall not be added to the amount
owing under the Mortgage Loan for the purpose of calculating monthly
distributions to Certificateholders, notwithstanding that the terms of the
Mortgage Loan so permit. Such costs shall be recoverable by the Master Servicer
or a Sub-Servicer out of related late payments by the Mortgagor or out of
Insurance Proceeds or Liquidation Proceeds or by the Master Servicer from the
Repurchase Price, to the extent permitted by Section 4.03.

          (d) No earthquake or other additional insurance is to be required of
any Mortgagor or maintained on property acquired with respect to a Security
Instrument other than pursuant to such applicable laws and regulations as shall
at any time be in force and shall require such additional insurance. Each year,
in accordance with standards and procedures required by Freddie Mac, the Master
Servicer shall perform a review of the Mortgage Loans to determine which, if
any, of the Mortgaged Properties are located in a federally designated special
flood hazard area and for each Mortgaged Property found to be located in a
federally designated special flood hazard area, the Master Servicer shall use
its best reasonable efforts to cause flood insurance (to the extent available
and in accordance with mortgage servicing industry practice) to be maintained
with respect to the related Mortgage Loans and REO Properties. Such flood
insurance shall cover the Mortgaged Property, including all items taken into
account in arriving at the Appraised Value on which the Mortgage Loan was based,
and shall be in an amount equal to the lesser of (i) the Outstanding Principal
Balance of the related Mortgage Loan and (ii) the minimum amount required under
the terms of coverage to compensate for any damage or loss on a replacement cost
basis, but not more than the maximum amount of such insurance available for the
related Mortgaged Property under either the regular or emergency programs of the
National Flood Insurance Program (assuming that the area in which such Mortgaged
Property is located is participating in such program). Unless applicable state
law requires a higher deductible, the deductible on such flood insurance may not
exceed $1,000 or 1% of the applicable amount of coverage, whichever is less.

          (e) If insurance complying with Subsections 3.10(a) and (d) has not
been maintained and there shall have been a loss which would have been covered
by such insurance had it been maintained, the Master Servicer shall pay, or
cause the related Sub-Servicer to pay, for any necessary repairs.

          (f) The Master Servicer shall present, or cause the related
Sub-Servicer to present, if it is a permitted claimant, claims under the related
hazard insurance or flood insurance policy.

          (g) The Master Servicer shall obtain and maintain at its own expense
and for the duration of this Agreement a blanket fidelity bond and shall cause
each Sub-Servicer (or itself to the extent there are no Sub-Servicers) to obtain
and maintain an errors and omissions insurance policy covering such
Sub-Servicer's (or the Master Servicer's, if there are no Sub-Servicers)
officers, employees and other persons acting on its behalf in connection with
its activities under this Agreement. The amount of coverage shall be at least
equal to the coverage maintained by the Master Servicer acceptable to Fannie Mae
or Freddie Mac to service loans for it or otherwise in an amount as is
commercially available at a cost that is generally not regarded as excessive by
industry standards. The Master Servicer shall promptly notify the Trustee of any
material change in the terms of such bond or policy. The Master Servicer shall
provide annually to the Trustee a certificate of insurance that such bond and
policy are in effect. If any such bond or policy ceases to be in effect, the
Master Servicer shall, to the extent possible, give the Trustee ten days' notice
prior to any such cessation and shall use its best efforts to obtain a
comparable replacement bond or policy, as the case may be. Any amounts relating
to the Mortgage Loans collected under such bond or policy shall be remitted to
the appropriate subaccount of the Certificate Account to the extent that such
amounts have not previously been paid to such account.

          Section 3.11. DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS. (a) In any
case in which the Master Servicer is notified by any Mortgagor or Sub-Servicer
that a Mortgaged Property relating to a Mortgage Loan has been or is about to be
conveyed by the Mortgagor, the Master Servicer shall enforce, or shall instruct
such Sub-Servicer to enforce, any due-on-sale clause contained in the related
Security Instrument to the extent permitted under the terms of the related
Mortgage Note and by applicable law unless the Master Servicer reasonably
believes such enforcement is likely to result in legal action by the Mortgagor.
The Master Servicer or the related Sub-Servicer may purchase a Mortgage Loan at
the Repurchase Price when the Master Servicer requires acceleration of the
Mortgage Loan, as a result of such conveyance, but only if the Master Servicer
is satisfied, as evidenced by an Officer's Certificate delivered to the Trustee,
that either (i) such Mortgage Loan is in default or default is reasonably
foreseeable or (ii) if such Mortgage Loan is not in default or default is not
reasonably foreseeable, the Master Servicer will deliver a REMIC Opinion to the
Trustee and the Certificate Insurer. If the Master Servicer reasonably believes
that such due-on-sale clause cannot be enforced under applicable law or if the
Mortgage Loan does not contain a due-on-sale clause, the Master Servicer is
authorized, and may authorize any Sub-Servicer, to consent to a conveyance
subject to the lien of the Mortgage, and to take or enter into an assumption
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 related
Mortgage Note and unless prohibited by the terms of the applicable Mortgage Note
or applicable state law, such Mortgagor remains liable thereon, on condition,
however, that the related Mortgage Loan shall continue to be covered (if so
covered before the Master Servicer or the related Sub-Servicer enters into such
agreement) by any applicable Primary Mortgage Insurance Policy, FHA insurance or
VA guaranty. The Master Servicer shall notify the Trustee, whenever possible,
before the completion of such assumption agreement, and shall forward to the
Trustee the original copy of such assumption agreement, which copy shall be
added by the Trustee to the related Mortgage File and which 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. In connection with
any such assumption agreement, the interest rate on the related Mortgage Loan
shall not be changed and no other material alterations in the Mortgage Loan
shall be made unless such material alteration would not cause either of REMIC I
or REMIC II to fail to qualify as a REMIC for federal income tax purposes, as
evidenced by a REMIC Opinion. If the interest rate on an assumed Mortgage Loan
is increased due to both (i) permitted increases upon assumption under the terms
of such Mortgage Loan and (ii) all applicable restrictions hereunder being
satisfied, the Master Servicer shall, as part of the report to the Trustee and
the Seller pursuant to Section 6.07(b) hereof, provide therefor on a revised
Mortgage Loan Schedule. In any event, the Master Servicer shall advise the
Trustee in writing of the entry into of any material modification of a Mortgage
Loan in connection with an assumption and shall provide the Trustee with a copy
of the REMIC Opinion. Any fee or additional interest collected by the Master
Servicer or Sub-Servicer for consenting to any such conveyance or entering into
any such assumption agreement may be retained by the Master Servicer or the
related Sub-Servicer as additional servicing compensation.

          (b) Notwithstanding the foregoing paragraph or any other provision of
this Agreement, the Master Servicer shall not be deemed to be in default, breach
or any other violation of its obligations hereunder by reason of any assumption
of a Mortgage Loan by operation of law or any conveyance by the Mortgagor of the
related Mortgaged Property or assumption of a Mortgage Loan which the Master
Servicer reasonably believes, based on prudent servicing standards, it may be
restricted by law from preventing, for any reason whatsoever or if the exercise
of such right would impair or threaten to impair any recovery under any
applicable Insurance Policy, or, in the Master Servicer's judgment, be
reasonably, likely to result in legal action by the Mortgagor or would otherwise
materially adversely affect the Certificateholders or the Certificate Insurer.

          Section 3.12. REALIZATION UPON DEFAULTED MORTGAGE LOANS; TITLE,
MANAGEMENT AND DISPOSITION OF REO PROPERTY. (a) Subject to Subsection 3.12(b),
the Master Servicer shall, or shall direct the related Sub-Servicer to,
foreclose upon or otherwise comparably convert the ownership of properties
securing any Mortgage Loans that come into and continue in default and as to
which no satisfactory arrangements can be made for collection of delinquent
payments pursuant to Section 3.06 except that the Master Servicer shall not, and
shall not direct the related Sub-Servicer, if any, to, foreclose upon or
otherwise comparably convert a Mortgaged Property if there is evidence of
environmental hazards or toxic waste thereon and the Master Servicer determines
it would be imprudent to do so or not in accordance with appropriate servicing
standards. The Master Servicer may conclusively rely on results of third party
inspections from parties it reasonably believes are qualified to conduct such
inspections. In connection with such foreclosure or other conversion, the Master
Servicer in conjunction with the related Sub-Servicer, if any, shall use its
best reasonable efforts to preserve REO Property and to realize upon defaulted
Mortgage Loans in such manner as to maximize the receipt of principal and
interest by the Certificateholders, taking into account, among other things, the
timing of foreclosure and the considerations set forth in Subsection 3.12(b).
The foregoing is subject to the proviso that the Master Servicer shall not be
required to expend its own funds in connection with any foreclosure or towards
the restoration of any property unless it determines in good faith (i) that such
restoration or foreclosure will increase the proceeds of liquidation of the
Mortgage Loan to Certificateholders after reimbursement to itself for such
expenses and (ii) that such expenses will be recoverable to it either through
Liquidation Proceeds (respecting which it shall have priority for purposes of
reimbursements from the Certificate Account pursuant to Section 4.03) or through
Insurance Proceeds (respecting which it shall have similar priority). The Master
Servicer shall be responsible for all other costs and expenses incurred by it in
any such proceedings; PROVIDED, HOWEVER, that it shall be entitled to
reimbursement thereof (as well as its normal servicing compensation), and in
respect of the Master Servicer only, to receive Excess Liquidation Proceeds as
additional servicing compensation to the extent that transfers or withdrawals
from the Certificate Account with respect thereto are permitted under Section
4.03. Any income from or other funds (net of any income taxes) generated by REO
Property shall be deemed for purposes of this Agreement to be Insurance
Proceeds.

          (b) The Trust Fund shall not acquire any real property (or any
personal property incident to such real property) except in connection with a
default or imminent default of a Mortgage Loan. The deed or certificate of sale
of any REO Property (or any personal property incident to such real property)
shall be taken in the name of the Trustee, or its nominee, on behalf of the
Certificateholders. The Master Servicer, on behalf of the Trust Fund, shall
either sell any REO Property within three years after the close of the taxable
year in which the Trust Fund acquires ownership of such REO Property for
purposes of Section 860G(a)(8) of the Code or request from the Internal Revenue
Service, more than 60 days before the day on which the three-year grace period
would otherwise expire, an extension of the three-year grace period, unless the
Master Servicer shall have delivered to the Trustee an Opinion of Counsel,
addressed to the Trustee and the Master Servicer, to the effect that the holding
by the Trust Fund of such REO Property subsequent to such three year period
after its acquisition will not result in the imposition on the Trust Fund of
taxes on "prohibited transactions" thereof, as defined in Section 860F of the
Code, or cause REMIC I or REMIC II to fail to qualify as a REMIC under Federal
law at any time that any Certificates are outstanding. The Master Servicer shall
manage, acquire, conserve, protect and operate each REO Property for the
Certificateholders solely for the purpose of its prompt disposition and sale in
a manner which does not cause such REO Property to fail to qualify as
"foreclosure property" within the meaning of Section 860G(a)(8) of the Code or
result in the receipt by the Trust Fund of any "income from non-permitted
assets" within the meaning of Section 860F(a)(2)(B) of the Code, or any "net
income from foreclosure property" which is subject to taxation under the REMIC
Provisions.

          (c) The Master Servicer shall have full power and authority, subject
only to the specific requirements and prohibitions of this Agreement, to do any
and all things in connection with any REO Property as are consistent with the
manner in which the Master Servicer manages and operates similar property owned
by the Master Servicer or any of its Affiliates, all on such terms and for such
period as the Master Servicer deems to be in the best interests of
Certificateholders. Notwithstanding the foregoing, the Master Servicer shall
not:

               (i) permit the Trust Fund to enter into, renew or extend any
          lease with respect to any REO Property, if such lease by its terms
          will give rise to any income that does not constitute gross income of
          the character described in Section 856(d) of the Code ("Rents from
          Real Property");

               (ii) permit any amount to be received or accrued under any lease
          other than amounts that will constitute Rents from Real Property;

               (iii) authorize or permit any construction on any REO Property,
          other than the completion of a building or other improvement thereon,
          and then only if more than ten percent of the construction of such
          building or other improvement was completed before default on the
          related Mortgage Loan became imminent, all within the meaning of
          Section 856(e)(4)(B) of the Code; or

               (iv) allow any Person (other than an Independent Contractor) to
          Directly Operate any REO Property on any date more than 90 days after
          its date of acquisition by the Trust Fund;

          unless, in any such case, the Master Servicer has obtained an Opinion
of Counsel, provided to the Trustee, to the effect that such action will not
cause such REO Property to fail to qualify as "foreclosure property" within the
meaning of Section 860G(a)(8) of the Code at any time that it is held by the
Trust Fund, in which case the Master Servicer may take such actions as are
specified in such Opinion of Counsel.

          The Master Servicer may contract with any Independent Contractor for
the operation and management of any REO Property, provided that:

               (i) the terms and conditions of any such contract shall not be
          inconsistent herewith;

               (v) any such contract shall require, or shall be administered to
          require, that the Independent Contractor pay all costs and expenses
          incurred in connection with the operation and management of such REO
          Property, including those listed above and remit all related revenues
          (net of such costs and expenses) to the Master Servicer as soon as
          practicable, but in no event later than thirty days following the
          receipt thereof by such Independent Contractor;

               (vi) none of the provisions of this Section 3.12(c) relating to
          any such contract or to actions taken through any such Independent
          Contractor shall be deemed to relieve the Master Servicer of any of
          its duties and obligations to the Trustee on behalf of the
          Certificateholders with respect to the operation and management of any
          such REO Property; and

               (vii) the Master Servicer shall be obligated with respect thereto
          to the same extent as if it alone were performing all duties and
          obligations in connection with the operation and management of such
          REO Property.

          The Master Servicer shall be entitled to enter into any agreement with
any Independent Contractor performing services for it related to its duties and
obligations hereunder for indemnification of the Master Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. The Master Servicer shall be solely liable for
all fees owed by it to any such Independent Contractor, irrespective of whether
the Master Servicer's compensation pursuant to hereto is sufficient to pay such
fees.

          (d) Subject to the time constraints set forth in Subsection 3.12(b),
each sale or other disposition of any REO Property on behalf of the Trust Fund
shall be carried out by the Master Servicer at such price and upon such terms
and conditions as the Master Servicer shall deem necessary or advisable and as
shall be normal and usual in its general servicing activities. Any sale or other
disposition of any REO Property shall be for cash only (unless changes in the
REMIC Provisions made subsequent to the Startup Day allow a sale for other
consideration).

          (e) The Master Servicer shall file information returns with respect to
the receipt of mortgage interest received in a trade or business, reports of
foreclosures and abandonments of any Mortgaged Property and cancellation of
indebtedness income with respect to any Mortgaged Property as required by
Sections 6050H, 6050J and 6050P of the Code, respectively. Such reports shall be
in form and substance sufficient to meet the reporting requirements imposed by
such Sections 6050H, 6050J and 6050P of the Code.

          Section 3.13. TRUSTEE TO COOPERATE; RELEASE OF MORTGAGE FILES. (a)
Upon payment in full of any Mortgage Loan or the receipt by the Master Servicer
of a notification that payment in full will be escrowed in a manner customary
for such purposes, the Master Servicer will immediately notify the Trustee by
sending two copies of a Request for Release signed by a Servicing Officer in the
form of Exhibit D or in a mutually agreeable electronic format which will, in
lieu of a signature on its face, originate from a Servicing Officer (which
certification shall include a statement to the effect that all amounts received
or to be received in connection with such payment which are required to be
deposited in the Certificate Account have been or will be so deposited in the
appropriate subaccount thereof) and shall request delivery to the Master
Servicer or a Sub-Servicer, as the case may be, of the Mortgage File. Upon
receipt of such certification and request, the Trustee shall promptly release
the related Mortgage File to the Master Servicer or a Sub-Servicer and execute
and deliver to the Master Servicer, without recourse, the request for
reconveyance, deed of reconveyance or release or satisfaction of mortgage or
such instrument releasing the lien of the Security Instrument (furnished by the
Master Servicer), together with the Mortgage Note with written evidence of
cancellation thereon. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Certificate
Account.

          (b) From time to time as is appropriate for the servicing or
foreclosure of any Mortgage Loan or collection under a Required Insurance
Policy, the Master Servicer shall deliver to the Trustee two copies of a Request
for Release signed by a Servicing Officer on behalf of the Master Servicer in
substantially the form attached as Exhibit D hereto or in a mutually agreeable
electronic format which will, in lieu of a signature on its face, originate from
a Servicing Officer. Upon receipt of the Request for Release, the Trustee shall
deliver the Mortgage File or any document therein to the Master Servicer or
Sub-Servicer, as the case may be.

          (c) The Master Servicer shall cause each Mortgage File released
pursuant to Subsection 3.13(b) to be returned to the Trustee when the need
therefor no longer exists, and in any event within 21 days of the Master
Servicer's receipt thereof, unless the Mortgage Loan has become a Liquidated
Mortgage Loan and the Liquidation Proceeds relating to the Mortgage Loan have
been deposited in the appropriate subaccount of the Certificate Account or such
Mortgage File is being used to pursue foreclosure or other legal proceedings.
Prior to return of a Mortgage File to the Trustee, the Master Servicer, the
related Insurer or Sub-Servicer to whom such file was delivered shall retain
such file in its respective control unless the Mortgage File has been delivered
to an attorney, or to a public trustee or other public official as required by
law, to initiate or pursue legal action or other proceedings for the foreclosure
of the Mortgaged Property either judicially or non-judicially, and the Master
Servicer has delivered to the Trustee a certificate of a Servicing Officer
certifying as to the name and address of the Person to which such Mortgage File
was delivered and the purpose or purposes of such delivery. If a Mortgage Loan
becomes a Liquidated Mortgage Loan, the Master Servicer shall deliver the
Request for Release with respect thereto to the Trustee upon deposit of the
related Liquidation Proceeds in the appropriate subaccount of the Certificate
Account.

          (d) The Trustee shall execute and deliver to the Master Servicer any
court pleadings, requests for trustee's sale or other documents furnished to the
Trustee necessary or advisable 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. Together with such documents or pleadings
the Master Servicer shall deliver to the Trustee a certificate of a Servicing
Officer in which it requests the Trustee to execute the pleadings or documents.
The certificate shall certify and explain the reasons for which the pleadings or
documents are required. It shall further certify that the Trustee's execution
and delivery of the pleadings or documents will not invalidate any insurance
coverage under the Required Insurance Policies or invalidate or otherwise affect
the lien of the Security Instrument, except for the termination of such a lien
upon completion of the foreclosure or trustee's sale.

          Section 3.14. SERVICING AND MASTER SERVICING COMPENSATION. (a) As
compensation for its activities hereunder, the Master Servicer shall be entitled
to receive the Master Servicing Fee from full payments of accrued interest on
each Mortgage Loan.

          (b) The Master Servicer may retain additional servicing compensation
in the form of prepayment charges, if any, assumption fees, tax service fees,
fees for statement of account or payoff, late payment charges, interest on
amounts deposited in any Accounts (other than the Certificate Account and the
Accrued Interest Account) or Permitted Investments of such amounts, or
otherwise. The Master Servicer is also entitled to receive Excess Liquidation
Proceeds as additional servicing compensation. The Master Servicer shall be
required to pay all expenses it incurs in connection with servicing activities
under this Agreement, including fees and expenses to Sub-Servicers, and shall
not be entitled to reimbursement except as provided in this Agreement. Expenses
to be paid by the Master Servicer under this Subsection 3.14(b) shall include
payment of the expenses of the accountants retained pursuant to Section 3.16.

          Section 3.15. ANNUAL STATEMENT OF COMPLIANCE. Within 120 days after
the last day of each fiscal year of the Master Servicer, currently November 30,
commencing November 2002, the Master Servicer at its own expense, shall deliver
to the Trustee, with a copy to the Rating Agency and the Certificate Insurer, an
Officer's Certificate stating, as to the signer thereof, that (i) a review of
the activities of the Master Servicer during the preceding fiscal year or
applicable portion thereof and of performance under this Agreement has been made
under such officer's supervision, (ii) to the best of such officer's knowledge,
based on such review, the Master Servicer has fulfilled all its obligations
under this Agreement for such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officer and the nature and status thereof including the steps being taken by the
Master Servicer to remedy such default; (iii) a review of the activities of each
Sub-Servicer, if any, during the Sub-Servicer's most recently ended fiscal year
on or prior to such November 30th and its performance under its Sub-Servicing
Agreement has been made under such Officer's supervision; and (iv) to the best
of the Servicing Officer's knowledge, based on his review and the certification
of an officer of the Sub-Servicer (unless the Servicing Officer has reason to
believe that reliance on such certification is not justified), either each
Sub-Servicer has performed and fulfilled its duties, responsibilities and
obligations under this Agreement and its Sub-Servicing Agreement in all material
respects throughout the year, or, if there has been a default in performance or
fulfillment of any such duties, responsibilities or obligations, specifying the
nature and status of each such default known to the Servicing Officer. Copies of
such statements shall be provided by the Master Servicer to the
Certificateholders upon request or by the Trustee at the expense of the Master
Servicer should the Master Servicer fail to provide such copies.

          Section 3.16. ANNUAL INDEPENDENT PUBLIC ACCOUNTANTS' SERVICING REPORT.
(a) Within 120 days after the last day of each fiscal year of the Master
Servicer, currently November, commencing November 2002, the Master Servicer, at
its expense, shall cause a firm of Independent public accountants who are
members of the American Institute of Certified Public Accountants to furnish a
statement to the Master Servicer, which will be provided to the Trustee, the
Certificate Insurer and the Rating Agency to the effect that, in connection with
the firm's examination of the Master Servicer's overall servicing activities for
such fiscal year conducted in accordance with the requirements of the Uniform
Single Attestation Program for Mortgage Bankers, nothing came to their attention
that indicated that the Master Servicer was not in compliance with Sections
3.07, 3.15, 4.01, 4.02 and 4.03 except for (i) such exceptions as such firm
believes to be immaterial and (ii) such other exceptions as are set forth in
such statement. In connection with the engagement to deliver any such report (or
other accountants' report or certificate hereunder) the Trustee is authorized
and directed to enter into such agreed-upon-procedures or engagement letter as
such accountants may request and shall be indemnified hereunder in so doing.

          (b) Within 120 days after the last day of the fiscal year of each
Sub-Servicer or a Master Servicer other than EMC or the Trustee, commencing with
the fiscal year ending in 2002, the Master Servicer, at its expense, shall
furnish to the Trustee the most recently available letter or letters from one or
more firms of Independent certified public accountants who are members of the
American Institute of Certified Public Accountants reporting the results of such
firm's examination of the servicing activities and procedures of any
Sub-Servicer and any Master Servicer (other than EMC or the Trustee) in
accordance with the requirements of the Uniform Single Attestation Program for
Mortgage Bankers, or such other program as may be certified as being comparable
by such accountants.

          Section 3.17. REMIC-RELATED COVENANTS. For as long as REMIC I or REMIC
II shall exist, the Master Servicer and the Trustee shall, subject to Article
IX, act in accordance herewith to treat REMIC I and REMIC II as REMICs. In
particular, the Trustee shall not (a) sell or permit the sale (to the extent
that it has actual knowledge of such sale) of all or any portion of the Mortgage
Loans or of any Permitted Investment 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 of a Mortgage Loan pursuant to Section
2.04 or in connection with a repurchase of a Mortgage Loan pursuant to this
Agreement, accept any contribution to REMIC I or REMIC II after the Startup Day
without receipt of a REMIC Opinion.

          Section 3.18. ADDITIONAL INFORMATION. The Master Servicer agrees to
furnish the Seller and the Certificate Insurer from time to time upon reasonable
request, such further information, reports and financial statements as the
Seller or the Certificate Insurer deems appropriate to prepare and file any
necessary reports with the Securities and Exchange Commission.

          Section 3.19. OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS. The
Master Servicer shall have the right, but not the obligation, to purchase any
Mortgage Loan that as of the first day of a calendar quarter is a Defaulted
Mortgage Loan, at the Repurchase Price; PROVIDED, HOWEVER, that (i) such
Mortgage Loan must, at the time of purchase by the Master Servicer, still be
delinquent in payment by 91 days or more and (ii) the right of the Master
Servicer hereunder to purchase such Mortgage Loan shall, if unexercised,
terminate on the day prior to the last day of such calendar quarter; PROVIDED
FURTHER, that such right of the Master Servicer with respect to such Mortgage
Loan shall be reinstated if such Mortgage Loan shall, if following such Mortgage
Loan's again becoming current in payment, it thereafter again becomes delinquent
in payment by 91 days or more. In such event, the applicable calendar quarter
for purposes of exercise by the Master Servicer of its right of purchase of such
Mortgage Loan hereunder shall be the calendar quarter immediately succeeding
such Mortgage Loan's having again become 91 days delinquent in payment. Such
optional right of repurchase of Defaulted Mortgage Loans by the Master Servicer
is subject to the further limitation that, should the Master Servicer have
purchased Defaulted Mortgage Loans pursuant to this Section 3.19 equal to 2% of
the Cut-Off Date Scheduled Principal Balance, it may thereafter only exercise
such option with respect to a Defaulted Mortgage Loan that is the greatest
number of days delinquent relative to other Defaulted Mortgage Loans at the time
of such repurchase, and must provide the Trustee and the Certificate Insurer
with a REMIC Opinion satisfactory to the Certificate Insurer in connection with
each such purchase. Any such purchase shall be accomplished as provided in
Subsection 2.02(c) hereof.

          Section 3.20. REQUIRED PURCHASE OF RESTRICTED LOANS. BSMCC agrees that
if the Master Servicer has not theretofore purchased a Restricted Loan pursuant
to Section 3.19, it will purchase from the Trust Fund at the Repurchase Price
any Restricted Loan for which (i) it receives notice from the Master Servicer
that title is about to be taken to the related Mortgaged Property as REO
Property on behalf of the Trust Fund and (ii) the Foreclosure Balance of such
Restricted Loan, plus the aggregate Foreclosure Balances as previously
determined by the Master Servicer for Restricted Loans in the same Mortgage Loan
Group that are currently held as REO Property, exceeds 0.75% of the then-current
aggregate basis of the assets in REMIC I. The aggregate basis of the assets of
REMIC I for this purpose is the basis of all REMIC I's assets as determined for
purposes of the most recent Form 1066 (and in the case of any period prior to
the first filing of Form 1066, the issue price of all interests issued by REMIC
I), properly adjusted for estimated changes to such basis. Any such purchase
shall be accomplished as provided in Subsection 2.02(c) hereof.

          Section 3.21. REPORTS FILED WITH THE SECURITIES AND EXCHANGE
COMMISSION; ADDITIONAL INFORMATION. Within 15 days after each Distribution Date,
the Trustee shall, in accordance with industry standards, file with the
Commission via the Electronic Data Gathering and Retrieval System ("EDGAR"), a
Form 8-K with a copy of the statement furnished by the Trustee to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
January 30, 2002, the Trustee 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, 2002, the Trustee shall
file a Form 10-K, in substance conforming to industry standards, with respect to
the Trust Fund. The Seller hereby grants to the Trustee a limited power of
attorney to execute and file each such document on behalf of the Seller. Such
power of attorney shall continue until the earlier of (i) receipt by the Trustee
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
Trustee, 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 Trustee reasonably deems appropriate to prepare and file
all necessary reports with the Commission. The Trustee shall have no
responsibility to file any items other than those specified in this Section
3.20; PROVIDED, however, that the Trustee shall 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 Trustee under the
Exchange Act shall be sent to: Structured Asset Mortgage Investments Inc., 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 Trustee in connection with this Section 3.20 shall not be
reimbursable from the Trust Fund.

                                   ARTICLE IV

                                    Accounts

          Section 4.01. PROTECTED ACCOUNTS. (a) The Master Servicer shall
establish and maintain if it is servicing the Mortgage Loans and shall require
each Sub-Servicer to establish and maintain a Protected Account complying with
the requirements set forth in this Section 4.01, with records to be kept with
respect thereto on a Mortgage Loan by Mortgage Loan basis, into which accounts
shall be deposited within two Business Days of receipt all collections of
principal and interest on any Mortgage Loan and with respect to any REO Property
received by the Master Servicer, or a Sub-Servicer, including Principal
Prepayments, Insurance Proceeds, Liquidation Proceeds, and advances made from
the Sub-Servicer's own funds (less servicing compensation as permitted by
Subsection 3.14(a)) and all other amounts to be deposited in the Protected
Accounts. The Master Servicer is hereby authorized to make withdrawals from and
deposits to the related Protected Accounts for purposes required or permitted by
this Agreement. All Protected Accounts shall be held in a Designated Depository
Institution and segregated on the books of such institution. The amount at any
time credited to a Protected Account shall be fully insured by the FDIC or, to
the extent that such balance exceeds the lesser of $100,000 or the limits of
such insurance, such excess must be transferred to the Certificate Account or
invested in Permitted Investments or may be deposited in a Rating Agency
Eligible Account in the name of the Trustee for the benefit of
Certificateholders and the Certificate Insurer and not commingled with any other
funds. The Master Servicer may, and the Master Servicer may permit a
Sub-Servicer to, transfer funds to other accounts (which shall for purposes
hereof be deemed to be Protected Accounts), commingle accounts, or to establish
Protected Accounts not conforming to the foregoing requirements, to the extent
that such other accounts or Protected Accounts are Rating Agency Eligible
Accounts.

          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
the Certificate Insurer and, except as provided in the preceding paragraph, not
commingled with any other funds, such Permitted Investments to mature, or to be
subject to redemption or withdrawal, no later than the date on which such funds
are required to be withdrawn for deposit in the Certificate Account, and shall
be held until required for such deposit. The income earned from Permitted
Investments made pursuant to this Section 4.01 shall be paid to the Master
Servicer or the related Sub-Servicer as additional compensation for its
obligations under this Agreement, and the risk of loss of moneys required to be
distributed to the Certificateholders resulting from such investments shall be
borne by and be the risk of the Master Servicer or the related Sub-Servicer. The
Master Servicer shall itself, or shall cause the related Sub-Servicer to,
deposit the amount of any such loss in the related Protected Account within two
Business Days of receipt of notification of such loss but not later than the
second Business Day prior to the Distribution Date on which the moneys so
invested are required to be distributed to the Certificateholders.

          (b) On or before (i) in the case of the Multifamily Loan, the 20th of
each calendar month (or if such day is not a Business Day, the immediately
succeeding Business Day) and (ii) in the case of any other Mortgage Loan, each
Funds Transfer Date, the Master Servicer shall withdraw or shall cause to be
withdrawn from the Protected Accounts and shall immediately deposit or cause to
be deposited in the Certificate Account (and, in the case of the Multifamily
Loan, the Master Servicer shall cause Reilly to withdraw from the applicable
Protected Account and immediately deposit into the Certificate Account) amounts
representing the following collections and payments (other than with respect to
principal of or interest on the Mortgage Loans due on or before the Cut-off Date
except for principal on Simple Interest Loans due on or before the Cut-Off Date
but received after the Cut-Off Date):

               (i) Monthly Payments on the Mortgage Loans received or any
          portion thereof advanced by the Master Servicer or Sub-Servicers which
          were due on or before the related Due Date, net of the amount thereof
          comprising servicing fees in excess of any compensating interest
          payments by the Master Servicer or by Sub-Servicers;

               (ii) Full Principal Prepayments and any Liquidation Proceeds
          received by the Master Servicer or Sub-Servicers with respect to such
          Mortgage Loans in the related Prepayment Period, with interest to the
          date of prepayment or liquidation, net of the amount thereof
          comprising the Master Servicing Fee due the Master Servicer;

               (iii) Partial prepayments of principal received by the Master
          Servicer or Sub-Servicers for such Mortgage Loans in the related
          Prepayment Period; and

               (iv) Any amount to be used as a Certificate Account Advance.

          (c) Withdrawals may be made from a Protected Account only to make
remittances as provided in Section 4.01(b) or 4.03; to reimburse the Master
Servicer or a Sub-Servicer for advances of principal and interest which have
been recovered by subsequent collection from the related Mortgagor; to remove
amounts deposited in error; to remove fees, charges or other such amounts
deposited on a temporary basis; or to clear and terminate the account at the
termination of this Agreement in accordance with Section 10.01. As provided in
Section 4.02(b) certain amounts otherwise due to the Master Servicer may be
retained by it and need not be deposited in the Certificate Account. Except as
provided in the foregoing sentences, prior to transfer of funds into the
Certificate Account pursuant to Section 4.01(b) for application as set forth in
Sections 4.02, 4.03 and 6.01, no withdrawals shall otherwise be made to pay any
expense, cost, fee, indemnity or liability of the Master Servicer or the
Trustee.

          (d) The Master Servicer shall deliver to the Trustee on or prior to
the Determination Date in each month a statement from the institution at which
each Protected Account is maintained showing deposits and withdrawals during the
prior month.

          Section 4.02. CERTIFICATE ACCOUNT. (a) The Trustee shall establish and
maintain in the name of the Trustee, for the benefit of the Certificateholders
and the Certificate Insurer, the Certificate Account as a segregated Rating
Agency Eligible Account or Accounts. The Certificate Account shall have two
separate subaccounts, one for each Mortgage Loan Group. The Trustee will deposit
in the appropriate subaccount of the Certificate Account as received the
following amounts:

               (i) Any amounts withdrawn from a Protected Account pursuant to
          Subsection 4.01(b);

               (ii) Any Monthly Advance and any Compensating Interest Payments;

               (iii) Any Insurance Proceeds or Liquidation Proceeds received by
          the Master Servicer which were not deposited in a Protected Account;

               (iv) The Repurchase Price, with respect to any Mortgage Loans
          purchased pursuant to Sections 2.02, 2.03A, 3.19 or 3.20, any amounts
          which are to be treated pursuant to Section 2.04 as the payment of
          such Repurchase Price, and all proceeds of any Mortgage Loans or
          property acquired with respect thereto repurchased by the Seller or
          its designee pursuant to Section 10.01;

               (v) Any amounts required to be deposited with respect to losses
          on Permitted Investments pursuant to Subsection 4.02(d) below; and

               (vi) Any other amounts received by the Master Servicer or the
          Trustee and required to be deposited in the Certificate Account
          pursuant to this Agreement.

          (b) All amounts (other than income earned on Permitted Investments)
deposited to the Certificate Account shall be held by the Trustee in the name of
the Trustee in trust for the benefit of the Certificateholders and the
Certificate Insurer and in accordance with the terms and provisions of this
Agreement, subject to the right of the Master Servicer to require the Trustee to
make withdrawals therefrom as provided herein. The foregoing requirements for
crediting the Certificate Account shall be exclusive, it being understood and
agreed that, without limiting the generality of the foregoing, payments in the
nature of (i) prepayment or late payment charges or assumption, tax service,
statement account or payoff, substitution, satisfaction, release and other like
fees and charges and (ii) the items enumerated in Subsections 4.03(a)(ii),
(iii), (iv), (v), (vii), (viii), (x) and (xii) need not be credited by the
Master Servicer or the related Sub-Servicer to the Certificate Account and may
be retained by the Master Servicer or the related Sub-Servicer as servicing
compensation. In the event that the Master Servicer shall deposit or cause to be
deposited to the Certificate Account any amount not required to be credited
thereto, the Trustee, upon receipt of a written request therefor signed by a
Servicing Officer of the Master Servicer, shall promptly transfer such amount to
the Master Servicer, any provision herein to the contrary notwithstanding.

          (c) The Certificate Account shall at all times be a Rating Agency
Eligible Account held by the Trustee in trust for the benefit of the
Certificateholders and the Certificate Insurer. The Certificate Account and the
funds deposited therein shall not be subject to, and shall be protected from,
all claims, liens and encumbrances of any creditors or depositors of the Trustee
(whether made directly, or indirectly through a liquidator or receiver of the
Trustee). In the sole discretion of the Trustee, the amount at any time credited
to the Certificate Account, other than amounts advanced by the Certificate
Insurer pursuant to the Certificate Insurance Policy, may be held uninvested or
may be invested, in the name of the Trustee or its nominee, for the benefit of
the Certificateholders and the Certificate Insurer, in such Permitted
Investments to be held by the Trustee as selected by it. All Permitted
Investments shall mature or be subject to redemption or withdrawal on or before,
and shall be held until, the next succeeding Distribution Date if the obligor
for such Permitted Investment is the Trustee or in the case of money market
funds for which the Trustee or an Affiliate is the advisor or manager or, if
such obligor is any other Person, the Business Day preceding such Distribution
Date. Any amounts advanced by the Certificate Insurer shall be held uninvested.

          (d) If funds on deposit in the Certificate Account are invested, any
income earned from Permitted Investments made pursuant to this Section 4.02
shall be paid to the Trustee, as compensation for its obligations under this
Agreement, and the risk of loss of moneys required to be distributed to the
Certificateholders resulting from such investments shall be borne by and be the
risk of the Trustee. The amount of any such loss shall be deposited by the
Trustee into the Certificate Account within two Business Days of receipt of
notification of such loss but not later than the Distribution Date on which the
moneys so invested are required to be distributed to the Certificateholders.

          Section 4.03. PERMITTED WITHDRAWALS AND TRANSFERS FROM THE CERTIFICATE
ACCOUNT. (a) The Trustee will, from time to time on demand of the Master
Servicer, make or cause to be made such withdrawals or transfers from the
Certificate Account as the Master Servicer has designated for such transfer or
withdrawal as specified in a certificate signed by a Servicing Officer (upon
which the Trustee may conclusively rely) for the following purposes (limited in
the case of amounts due the Master Servicer to those not withdrawn from the
Protected Account in accordance with the terms of this Agreement):

               (i) [Reserved];

               (ii) to reimburse the Master Servicer or any Sub-Servicer for any
          Monthly Advance or Servicing Advance of its own funds or any advance
          of such Sub-Servicer's own funds, the right of the Master Servicer or
          a Sub-Servicer to reimbursement pursuant to this subclause (ii) being
          limited to amounts received on a particular Mortgage Loan (including,
          for this purpose, the Repurchase Price therefor, Insurance Proceeds
          and Liquidation Proceeds) which represent late payments or recoveries
          of the principal of or interest on such Mortgage Loan respecting which
          such Monthly Advance or Servicing Advance was made;

               (iii) to reimburse the Master Servicer or any Sub-Servicer from
          Insurance Proceeds or Liquidation Proceeds relating to a particular
          Mortgage Loan for amounts expended by the Master Servicer or such
          Sub-Servicer pursuant to Section 3.12 in good faith in connection with
          the restoration of the related Mortgaged Property which was damaged by
          an Uninsured Cause or in connection with the liquidation of such
          Mortgage Loan;

               (iv) to reimburse the Master Servicer or any Sub-Servicer from
          Insurance Proceeds relating to a particular Mortgage Loan for Insured
          Expenses incurred with respect to such Mortgage Loan and to reimburse
          the Master Servicer or such Sub-Servicer from Liquidation Proceeds
          from a particular Mortgage Loan for Liquidation Expenses incurred with
          respect to such Mortgage Loan; PROVIDED THAT the Master Servicer shall
          not be entitled to reimbursement for Liquidation Expenses with respect
          to a Mortgage Loan to the extent that (i) any amounts with respect to
          such Mortgage Loan were paid as Excess Liquidation Proceeds pursuant
          to clause (xii) of this Subsection 4.03(a) to the Master Servicer; and
          (ii) such Liquidation Expenses were not included in the computation of
          such Excess Liquidation Proceeds;

               (v) to pay the Master Servicer or any Sub-Servicer (payment to
          any Sub-Servicer to be subject to prior payment to the Master Servicer
          of an amount equal to the Master Servicing Fee), as appropriate, from
          Liquidation Proceeds or Insurance Proceeds received in connection with
          the liquidation of any Mortgage Loan, the amount which it or such
          Sub-Servicer would have been entitled to receive under subclause (x)
          of this Subsection 4.03(a) as servicing compensation on account of
          each defaulted scheduled payment on such Mortgage Loan if paid in a
          timely manner by the related Mortgagor, but only to the extent that
          the aggregate of Liquidation Proceeds and Insurance Proceeds with
          respect to such Mortgage Loan, after any reimbursement to the Master
          Servicer or any Sub-Servicer, pursuant to subclauses (ii), (iii), (iv)
          and (vii) of this Subsection 4.03(a), exceeds the Outstanding
          Principal Balance of such Mortgage Loan plus accrued and unpaid
          interest thereon at the related Mortgage Rate less the Master
          Servicing Fee Rate to but not including the date of payment;

               (vi) unless any such amount has already been deducted therefrom,
          to pay the Master Servicer or any Sub-Servicer (payment to any
          Sub-Servicer to be subject to prior payment to the Master Servicer of
          the portion of the Master Servicing Fee which the Master Servicer is
          entitled to retain as evidenced in writing to the Trustee by the
          Master Servicer, as appropriate) from the Repurchase Price for any
          Mortgage Loan, the amount which it or such Sub-Servicer would have
          been entitled to receive under subclause (x) of this Subsection
          4.03(a) as servicing compensation, but only to the extent that the
          Repurchase Price with respect to such Mortgage Loan after any
          reimbursement to the related Master Servicer and Sub-Servicer pursuant
          to subclauses (ii) and (vii) of this Subsection 4.03(a) exceeds the
          Outstanding Principal Balance of such Mortgage Loan plus accrued and
          unpaid interest thereon at the related Mortgage Rate less the Master
          Servicing Fee Rate through the last day of the month of repurchase;

               (vii) to the extent not reimbursed pursuant to clause (iii) or
          (iv), to reimburse the Master Servicer or any Sub-Servicer for
          Servicing Advances pursuant to Sections 3.07, 3.09 and 3.10, the right
          to reimbursement pursuant to this subclause being limited to amounts
          received on the related Mortgage Loan (including, for this purpose,
          the Repurchase Price therefor, Insurance Proceeds and Liquidation
          Proceeds) which represent late recoveries of the payments for which
          such advances were made; (viii) to pay the Master Servicer or any
          Sub-Servicer, as the case may be, with respect to each Mortgage Loan
          that has been purchased pursuant to Section 2.02, 2.03A, 2.04, 3.19 or
          10.01 or BSMCC with respect to each Mortgage Loan purchased pursuant
          to Section 3.20, all amounts received thereon, representing recoveries
          of principal that reduce the Outstanding Principal Balance of the
          related Mortgage Loan below the Outstanding Principal Balance used in
          calculating the Repurchase Price or representing interest included in
          the calculation of the Repurchase Price or accrued after the end of
          the month during which such repurchase occurs;

               (ix) to reimburse the Master Servicer or any Sub-Servicer for any
          Monthly Advance or Servicing Advance, after a Realized Loss has been
          allocated with respect to the related Mortgage Loan if the Monthly
          Advance or Servicing Advance has not been reimbursed pursuant to
          clauses (ii) and (vii), such reimbursement to come from the subaccount
          relating to the Mortgage Loan Group of which the related Mortgage Loan
          is part;

               (x) to pay the Master Servicer and any Sub-Servicer servicing
          compensation as set forth in Section 3.14;

               (xi) on each Distribution Date, to reimburse the Master Servicer
          for expenses, costs, indemnification and liabilities incurred by and
          reimbursable to it pursuant to Subsection 7.04(c) and (d), in an
          amount not to exceed $7,500 per month, which, if not specifically
          allocable to a Mortgage Loan Group, shall be allocated between the
          subaccounts pro rata, based upon the aggregate Scheduled Principal
          Balance of the related Mortgage Loan Group as of the close of business
          on the last day of the immediately preceding Due Period (any such
          amounts in excess of $7,500 being subject to reimbursement in
          accordance with Section 6.01(a);

               (xii) pay to the Master Servicer, as additional servicing
          compensation, any Excess Liquidation Proceeds;

               (xiii) to clear and terminate the Certificate Account pursuant to
          Section 10.01; and

               (xiv) to remove amounts deposited in error.

          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 Certificate Account pursuant to subclauses (i) through
(vii), inclusive, and (ix) 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 Certificate Account under Section
4.02(b).

          (b) On each Distribution Date, the Trustee shall make the following
payments in the priority set forth from Available Funds in the Certificate
Account (with respect to clause (i) and (ii), such payments to be allocated
between Group Available Funds in each subaccount pro rata, based on the
aggregate Scheduled Principal Balance of the related Mortgage Loan Group as of
the close of business on the last day of the immediately preceding Due Period):

               (i) First, expenses, costs, liabilities, indemnities and other
          amounts incurred by and reimbursable to the Trustee in accordance with
          Sections 8.02 and 9.05(a) and (b), in an amount not to exceed $7,500,
          shall be paid to the Trustee (any such amounts in excess of $7,500
          being subject to reimbursement in accordance with Section 6.01(a).);

               (ii) Second, the Certificate Insurer Premium shall be paid to the
          Certificate Insurer in accordance with the Insurance Agreement; and

          Certificates and the Certificate Insurer shall be payable in
          accordance with Section 6.01.

          (c) Notwithstanding the provisions of this Section 4.03, the Master
Servicer may, but is not required to, allow the Sub-Servicers to deduct from
amounts received by them or from the related Protected Account, prior to deposit
in the Certificate Account, any portion to which such Sub-Servicers are entitled
as servicing compensation (including income on Permitted Investments) or
reimbursement of any reimbursable advances made by such Sub-Servicers.

          (d) The Trustee shall be permitted to make withdrawals or transfers
from the Certificate Account to remove amounts deposited by the Trustee in
error.

the name of the Trustee for the benefit of the Certificateholders, the Accrued
Interest Account as a Rating Agency Eligible Account. The Accrued Interest
Account shall not be invested. On the Closing Date, EMC shall deposit an amount
equal to the Accrued Interest Reimbursement Amount into the Accrued Interest
Account. On the Distribution Date in November 2001, the Trustee shall distribute
the Accrued Interest Reimbursement Amount to the Certificateholders in
accordance with Section 6.01 and thereafter close the Accrued Interest Account.

                        The Certificate Insurance Policy

          Section 4A.01. CLAIMS UNDER THE CERTIFICATE INSURANCE POLICY. (a) On
each Determination Date, the Trustee shall, based on the related Loan Summary
and Remittance Report delivered by the Master Servicer, determine whether a
Deficiency Amount exists. If a Deficiency Amount then exists, the Trustee shall
make a request for payment of the Deficiency Amount by the Certificate Insurer
no later than 12:00 p.m. on the third Business Day prior to the related
Distribution Date in the manner provided in the Certificate Insurance Policy.
All claims made by the Trustee under the Certificate Insurance Policy shall be
made in accordance with and subject to the terms of the Certificate Insurance
Policy.

          (b) The Trustee shall (i) receive, as attorney-in-fact of each Holder
of a Senior Certificate, any Insured Payment paid to the Trustee under the
Certificate Insurance Policy, (ii) deposit any such Insured Payment in the
Certificate Account and hold any such Insured Payment therein uninvested and
(iii) distribute the portion thereof constituting the Deficiency Amount to the
related Holder of a Senior Certificate pursuant to Section 6.01(a). The portion
of any Insured Payment constituting a Preference Amount shall, if received by
the Trustee, be paid by the Trustee in accordance with the provisions of the
Certificate Insurance Policy. Any Insured Payment made by the Certificate
Insurer under the Certificate Insurance Policy and disbursed in accordance
herewith or in accordance with the provisions of the Certificate Insurance
Policy shall not be considered payment by the Trust with respect to such
Certificates, and shall not discharge the obligations of the Trust with respect
thereto. The Certificate Insurer shall, to the extent it makes any payment with
respect to Senior Certificates, become subrogated to the rights of the
recipients of such payments to the extent of such payments. Subject to and
conditioned upon any payment with respect to Senior Certificates by or on behalf
of the Certificate Insurer under the Certificate Insurance Policy, the Trustee
shall on behalf of the Holders of the related Senior Certificates assign to the
Certificate Insurer all rights to the payment of interest or principal with
respect to such Senior Certificates which are then due for payment to the extent
of all payments made by the Certificate Insurer. To evidence such subrogation,
the Trustee shall note the Certificate Insurer's rights as subrogee upon the
Certificate Register upon receipt from the Certificate Insurer of proof of
payment by the Certificate Insurer under the Certificate Insurance Policy.

          (c) The Trustee shall be entitled to enforce on behalf of the Senior
Certificateholders the obligations of the Certificate Insurer under the
Certificate Insurance Policy. Notwithstanding any other provision of this
Agreement, the Senior Certificateholders are not entitled to make a claim for
any Deficiency Amount directly under the Certificate Insurance Policy or
institute proceedings directly against the Certificate Insurer.

          Section 4A.02. RIGHTS OF THE CERTIFICATE INSURER. Each Senior
Certificateholder by purchase of a Senior Certificate held by it acknowledges
and agrees that the Certificate Insurer shall have certain rights hereunder for
so long as the Senior Certificates are outstanding or any amounts are owed to
the Certificate Insurer pursuant to the Certificate Insurance Policy, and the
Certificate Insurer is not in default thereunder. Notwithstanding anything to
the contrary contained herein, so long as a default by the Certificate Insurer
pursuant to the Certificate Insurance Policy has occurred and is continuing, any
provision giving the Certificate Insurer the right to direct, appoint or consent
to, approve of, or take any action under this Agreement or the Seller Contract,
irrespective of whether such rights have been either granted directly to the
Certificate Insurer, to the Certificate Insurer as a third-party beneficiary or
exercised on behalf of the Senior Certificateholders, shall be inoperative
during the period of such default and such right shall instead vest in the
Trustee acting at the written direction of Senior Certificateholders (without
regard to Section 11.06). The Certificate Insurer may disclaim any of its rights
and powers under this Agreement (but not its duties and obligations under the
Certificate Insurance Policy or the Insurance Agreement) upon delivery of a
written notice to the Trustee. Unless otherwise specified herein, the
Certificate Insurer may give or withhold any consent hereunder in its reasonable
discretion.

                                   ARTICLE V

                                  Certificates

          Section 5.01. CERTIFICATES. (a) The Depository, the Seller and the
Trustee have entered into a Depository Agreement dated as of October 17, 2001
(the "Depository Agreement"). Except for the Residual Certificates, the
Individual Certificates and as provided in Subsection 5.01(b), the Certificates
shall at all times remain registered in the name of the Depository or its
nominee and at all times: (i) registration of such Certificates may not be
transferred by the Trustee except to a successor to the Depository; (ii)
ownership and transfers of registration of such Certificates on the books of the
Depository shall be governed by applicable rules established by the Depository;
(iii) the Depository may collect its usual and customary fees, charges and
expenses from its Depository Participants; (iv) the Trustee shall deal with the
Depository for all purposes (including the making of a distribution) as
representative of such Certificate Owners of the respective Class of
Certificates, and including for purposes of exercising the rights of
Certificateholders under this Agreement, and requests and directions for and
votes of such representative shall not be deemed to be inconsistent if they are
made with respect to different Certificate Owners; and (v) the Trustee may rely
and shall be fully protected in relying upon information furnished by the
Depository with respect to its Depository Participants.

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

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

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

          (c) REMIC I will be evidenced by (x) the Class 1-a, Class 2-a, Class
1-b, Class 2-b and Class Q Certificates (the "REMIC I Regular Certificates"),
which will be uncertificated and non-transferable and are hereby designated as
the "regular interests" in REMIC I and (y) the Class R-1 Certificate, which is
hereby designated as the single "residual interest" in REMIC I. The assets of
REMIC I are, for federal income tax purposes, the assets of the Trust Fund.
Distributions shall be made first, so as to keep the Class 1-a and Class 2-a
Certificates equal to 0.1% of the Pool 1 Balance AND 0.1% of the Pool 2 Balance,
respectively; second, to the Class 1-b and Class 2-b Certificates, so that their
principal balances are equal to 0.1% of the excess of the Pool 1 Balance over
the principal balance of the Class A-1 Certificates AND 0.1% of the excess of
the Pool 2 Balance over the principal balance of the Class A-2 Certificates,
respectively (except that if any such excess is a larger number than in the
preceding distribution period, the least amount of principal shall be
distributed to the Class 1-b and Class 2-b Certificates such that the
Subordinate Balance Ratio is maintained); and third, any remaining principal to
the Class Q Certificates. Realized Losses shall be applied to the outstanding
balance of each class of REMIC I Certificates, after all distributions have been
made on each Distribution Date first, so as to keep the Class 1-a and Class 2-a
Certificates equal to 0.1% of the Pool 1 Balance AND 0.1% of the Pool 2 Balance,
respectively; second, to the Class 1-b and Class 2-b Certificates, so that their
principal balances are equal to 0.1% of the excess of the Pool 1 Balance over
the principal balance of the Class A-1 Certificates AND 0.1% of the excess of
the Pool 2 Balance over the principal balance of the Class A-2 Certificates,
respectively (except that if any such excess is a larger number than in the
preceding distribution period, the least amount of principal shall be allocated
to the Class 1-b and Class 2-b Certificates such that the Subordinate Balance
Ratio is maintained); and third, the remaining Realized Losses shall be
allocated to the Class Q Certificate. The REMIC I Regular Certificates and the
Class R-1 Certificates will have the following designations and pass-through
rates:

     Group 1 Mortgage Loans as of the close of business on the last day of the
     Due Period immediately preceding the Due Period related to such
     Distribution Date, less the Certificate Insurer Rate.

(2)  For any Distribution Date, the weighted average of the Net Rates of the
     Group 2 Mortgage Loans as of the close of business on the last day of the
     Due Period immediately preceding the Due Period related to such
     Distribution Date, less the Certificate Insurer Rate.

(3)  For any Distribution Date, an amount equal to the weighted average of the
     pass-through rates of the Class 1-b and the Class 2-b Certificates on such
     Distribution Date, PROVIDED, HOWEVER, that (i) the pass-through rate of the
     Class 1-b Certificates shall be subject to both a cap and a floor equal to
     the weighted average of the Net Rates of the Group 1 Mortgage Loans as of
     the close of business on the last day of the Due Period immediately
     preceding the Due Period related to such Distribution Date and (ii) the
     pass-through rate of the Class 2-b Certificates shall be subject to both a
     cap and a floor equal to the weighted average of the Net Rates of the Group
     2 Mortgage Loans as of the close of business on the last day of the Due
     Period immediately preceding the Due Period related to such Distribution
     Date.

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

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

          (g) Each Class of Book-Entry Certificates will be registered as a
single Certificate of such Class held by a nominee of the Depository or the DTC
Custodian, and beneficial interests will be held by investors through the
book-entry facilities of the Depository in minimum denominations of $25,000 and
increments of $1.00 in excess thereof, except that one Certificate of each such
Class may be issued in a different amount so that the sum of the denominations
of all outstanding Certificates of such Class shall equal the Current Principal
Amount of such Class on the Closing Date. On the Closing Date, the Trustee shall
execute and countersign Physical Certificates all in an aggregate principal
amount that shall equal the Current Principal Amount of such Class on the
Closing Date. The Private Certificates (other than the Residual Certificates)
will be issued in certificated fully-registered form in minimum denominations of
$50,000 and increments of $1.00 in excess thereof, except that one Certificate
of each such Class may be issued in a different amount so that the sum of the
denominations of all outstanding Certificates of such Class shall equal the
Current Principal Amount of such Class on the Closing Date. The Residual
Certificates shall each be issued as a single certificate in certificated
fully-registered form with no principal balance. Each Class of Global
Certificates, if any, shall be issued in fully registered form in minimum dollar
denominations of $50,000 and integral multiples of $1.00 in excess thereof,
except that one Certificate of each Class may be in a different denomination so
that the sum of the denominations of all outstanding Certificates of such Class
shall equal the Current Principal Amount of such Class on the Closing Date. On
the Closing Date, the Trustee shall execute and countersign (i) in the case of
each Class of Offered Certificates, the Certificate in the entire Current
Principal Amount of the respective Class and (ii) in the case of each Class of
Private Certificates, all in an aggregate principal amount that shall equal the
Current Principal Amount of each such respective Class on the Closing Date. The
Certificates referred to in clause (i) and, if at any time there are to be
Global Certificates, the Global Certificates, shall be delivered by the Seller
to the Depository or pursuant to the Depository's instructions, shall be
delivered by the Seller on behalf of the Depository to and deposited with the
DTC Custodian. The Trustee shall sign the Certificates by facsimile or manual
signature and countersign them by manual signature on behalf of the Trustee by
one or more authorized signatories, each of whom shall be a Responsible Officer
of the Trustee or its agent. A Certificate bearing the manual and facsimile
signatures of individuals who were the authorized signatories of the Trustee or
its agent at the time of issuance shall bind the Trustee, notwithstanding that
such individuals or any of them have ceased to hold such positions prior to the
delivery of such Certificate.

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

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

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

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

          (l) The "latest possible maturity date" (for purposes of Treasury
Regulation Section 1.860G-1) for each of the regular interests in REMIC I and
REMIC II shall be the Assumed Final Distribution Date.

          (m) The Class R-1 and Class R-2 Certificates shall each be entitled to
all distributions from their respective REMICs, if any, that are not otherwise
provided for herein.

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

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

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

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

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

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

               (i) In the case of a beneficial interest in the Global
          Certificate being transferred to an Institutional Accredited Investor,
          such transferee shall be required to take delivery in the form of an
          Individual Certificate or Certificates and the Trustee shall register
          such transfer only upon compliance with the provisions of Subsection
          5.02(c)(ii).

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

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

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

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

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

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

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

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

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

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

          (h) Subject to the restrictions on transfer and exchange set forth in
this Section 5.02 and Sections 5.06 and 5.07, the holder of any Individual
Certificate may transfer or exchange the same in whole or in part (in an initial
certificate balance equal to the minimum authorized denomination set forth in
Section 5.01(g) above or any integral multiple of $1.00 in excess thereof) by
surrendering such Certificate at the Corporate Trust Office or at such other
office as may be designated by the Trustee for this purpose, or at the office of
any transfer agent, together with an executed instrument of assignment and
transfer satisfactory in form and substance to the Trustee in the case of
transfer and a written request for exchange in the case of exchange. The holder
of a beneficial interest in a Global Certificate may, subject to the rules and
procedures of the Depository, cause the Depository (or its nominee) to notify
the Trustee in writing of a request for transfer or exchange of such beneficial
interest for an Individual Certificate or Certificates. Following a proper
request for transfer or exchange, the Trustee shall, within five Business Days
of such request made at such Corporate Trust Office, sign, countersign and
deliver at such Corporate Trust Office, to the transferee (in the case of
transfer) or holder (in the case of exchange) or send by first class mail at the
risk of the transferee (in the case of transfer) or holder (in the case of
exchange) to such address as the transferee or holder, as applicable, may
request, an Individual Certificate or Certificates, as the case may require, for
a like aggregate Fractional Undivided Interest and in such authorized
denomination or denominations as may be requested. The presentation for transfer
or exchange of any Individual Certificate shall not be valid unless made at the
Corporate Trust Office or at such other office as may be designated by the
Trustee for this purpose by the registered holder in person, or by a duly
authorized attorney-in-fact. As of the Closing Date, the Trustee designates its
Corporate Trust Office as the office for accepting Certificates for transfer or
surrender in accordance with this Article V.

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

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

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

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

          (m) The following legend shall be placed on Certificates for each
Class of Subordinate Certificates, whether upon original issuance or upon
issuance of any other Certificate of any such Class in exchange therefor or upon
transfer thereof and each transfer of Certificates of such Classes shall be
subject to the provisions thereof:

     THIS CERTIFICATE MAY NOT BE ACQUIRED DIRECTLY OR INDIRECTLY BY, OR ON
     BEHALF OF, AN EMPLOYEE BENEFIT PLAN OR OTHER RETIREMENT ARRANGEMENT WHICH
     IS SUBJECT TO TITLE I OF THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF
     1974, AS AMENDED, AND/OR SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986,
     AS AMENDED, UNLESS THE PROPOSED TRANSFER AND/OR HOLDING OF A CERTIFICATE
     AND THE SERVICING, MANAGEMENT AND/OR OPERATION OF THE TRUST AND ITS ASSETS:
     (I) WILL NOT RESULT IN ANY PROHIBITED TRANSACTION WHICH IS NOT COVERED
     UNDER AN INDIVIDUAL OR CLASS PROHIBITED TRANSACTION EXEMPTION, INCLUDING,
     BUT NOT LIMITED TO, PROHIBITED TRANSACTION EXEMPTION ("PTE") 84-14, PTE
     91-38, PTE 90-1, PTE 95-60 OR PTE 96-23 AND (II) WILL NOT GIVE RISE TO ANY
     ADDITIONAL FIDUCIARY DUTIES ON THE PART OF THE MASTER SERVICER OR THE
     TRUSTEE, WHICH WILL BE DEEMED REPRESENTED BY AN OWNER OF A BOOK-ENTRY
     CERTIFICATE OR A GLOBAL CERTIFICATE AND WILL BE EVIDENCED BY A
     REPRESENTATION TO SUCH EFFECT BY OR ON BEHALF OF A HOLDER OF A PRIVATE
     CERTIFICATE.

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

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

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

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

          (b) No transfer, sale or other disposition of a Residual Certificate
(including a beneficial interest therein) may be made unless, prior to the
transfer, sale or other disposition of a Residual Certificate, the proposed
transferee (including the initial purchaser thereof) delivers to the Tax Matters
Person, the Seller and the Trustee an affidavit in the form attached hereto as
Exhibit E stating, among other things, that as of the date of such transfer (i)
such transferee is not any of (A) the United States, any state or political
subdivision thereof, any foreign government, any international organization, or
any agency or instrumentality of any of the foregoing (other than an
instrumentality that is a corporation all of whose activities are subject to tax
under Chapter 1 of Subtitle A of the Code and (except in the case of Freddie
Mac) a majority of whose board of directors is not selected by the United
States, or any state or political subdivision thereof), (B) any organization
that is exempt from any tax imposed by Chapter 1 of Subtitle A of the Code,
other than (x) a tax-exempt farmers' cooperative within the meaning of Section
521 of the Code or (y) an organization that is subject to the tax imposed by
Section 511 of the Code on "unrelated business taxable income" or (C) a
corporation operating on a cooperative basis that is engaged in furnishing
electric energy or providing telephone service to persons in rural areas (within
the meaning of Section 1381(a)(2)(C) of the Code) (any Person described in (A),
(B), or (C) being referred to herein as a "Disqualified Organization") and that
(ii) such transferee is not acquiring such Residual Certificate for the account
of a Disqualified Organization. Neither the Tax Matters Person nor the Seller
shall consent to a transfer of a Residual Certificate if it has actual knowledge
that any statement made in the affidavit issued pursuant to the preceding
sentence is not true. Notwithstanding any transfer, sale or other disposition of
a Residual Certificate to a Disqualified Organization, such transfer, sale or
other disposition shall be deemed to be of no legal force or effect whatsoever
and such Disqualified Organization shall not be deemed to be a Holder of a
Residual Certificate for any purpose hereunder, including, but not limited to,
the receipt of distributions thereon. If any purported transfer shall be in
violation of the provisions of this Subsection 5.05(b), then the prior Holder
thereof shall, upon discovery that the transfer of such Residual Certificate was
not in fact permitted by this Subsection 5.05(b), be restored to all rights as a
Holder thereof retroactive to the date of the purported transfer. None of the
Trustee, the Seller or the Tax Matters Person shall be under any liability to
any Person for any registration or transfer of a Residual Certificate that is
not permitted by this Subsection 5.05(b) or for making payments due on such
Residual Certificate to the purported Holder thereof or taking any other action
with respect to such purported Holder under the provisions of this Agreement so
long as the written affidavit referred to above was received with respect to
such transfer, and the Tax Matters Person, the Seller or the Trustee, as
applicable, had no actual knowledge, that it was untrue. The prior Holder shall
be entitled to recover from any purported Holder of a Residual Certificate that
was in fact not a permitted transferee under this Subsection 5.05(b) at the time
it became a Holder all payments made on such Residual Certificate. Each Holder
of a Residual Certificate, by acceptance thereof, shall be deemed for all
purposes to have consented to the provisions of this Subsection 5.05(b) and to
any amendment of this Agreement deemed necessary (whether as a result of new
legislation or otherwise) by counsel of the Tax Matters Person or the Seller to
ensure that the Residual Certificate is not transferred to a Disqualified
Organization and that any transfer of such Residual Certificate will not cause
the imposition of a tax upon the Trust or cause REMIC I or REMIC II to fail to
qualify as a REMIC.

          (c) Unless the Tax Matters Person and the Seller shall have consented
in writing (which consent may be withheld in such person's sole discretion), the
Residual Certificate (including a beneficial interest therein) may not be
purchased by or transferred to any person who is not a "United States person,"
as such term is defined in Section 7701(a)(30) of the Code.

          (d) By accepting a Residual Certificate, the purchaser thereof agrees
to be a Tax Matters Person, and appoints the Trustee to act as its agent with
respect to all matters concerning the tax obligations of the Trust, other than
those matters regarding transfer restrictions contained in this Section 5.05.

          Section 5.06. RESTRICTIONS ON TRANSFERABILITY OF PRIVATE CERTIFICATES.
(a) No offer, sale, transfer or other disposition (including pledge) of a
Private Certificate shall be made by any Holder thereof unless registered under
the Securities Act, or an exemption from the registration requirements of the
Securities Act and any applicable state securities or "Blue Sky" laws is
available and the prospective transferee (other than the Seller) of such
Certificate signs and delivers to the Trustee an Investment Letter, if the
transferee is an Institutional Accredited Investor, in the form set forth as
Exhibit F-1 hereto, or a Rule 144A Certificate, if the transferee is a QIB, in
the form set forth as Exhibit F-2 hereto. Notwithstanding the provisions of the
immediately preceding sentence, no restrictions shall apply with respect to the
transfer or registration of transfer of a beneficial interest in a Physical
Certificate that is a Global Certificate of a Class to a transferee that takes
delivery in the form of a beneficial interest in the Global Certificate of such
Class provided that each such transferee shall be deemed to have made such
representations and warranties contained in the Rule 144A Certificate as are
sufficient to establish that it is a QIB. In the case of a proposed transfer of
a Private Certificate to a transferee other than a QIB, the Trustee may require
an Opinion of Counsel that such transaction is exempt from the registration
requirements of the Securities Act. The cost of such opinion shall not be an
expense of the Trustee or the Trust Fund.

          (b) Each Private Certificate shall bear a Securities Legend.

          Section 5.07. ERISA RESTRICTIONS. (a) Subject to the provisions of
subsection (b), no Certificates of a Class of Individual Certificates may be
acquired directly or indirectly by, or on behalf of, an employee benefit plan or
other retirement arrangement which is subject to Title I of ERISA and/or Section
4975 of the Code (a "Plan"), unless the proposed transferee provides a
representation or certification to the Trustee substantially in the form of
Exhibit I hereto (upon which the Trustee is authorized to rely) to the effect
that the proposed transfer and/or holding of a Certificate and the servicing,
management and operation of the Trust: (i) will not result in a prohibited
transaction under Section 406 of ERISA or Section 4975 of the Code which is not
covered under an individual or class prohibited transaction exemption including
but not limited to Department of Labor Prohibited Transaction Exemption ("PTE")
84-14 (Class Exemption for Plan Asset Transactions Determined by Independent
Qualified Professional Asset Managers), PTE 91-38 (Class Exemption for Certain
Transactions Involving Bank Collective Investment Funds), PTE 90-1 (Class
Exemption for Certain Transactions Involving Insurance Company Pooled Separate
Accounts), PTE 95-60 (Class Exemption for Certain Transactions Involving
Insurance Company General Accounts) and PTCE 96-23 (Class Exemption for Plan
Asset Transactions Determined by In-House Asset Managers and (ii) will not give
rise to any additional fiduciary duties under ERISA on the part of the Master
Servicer or the Trustee.

          (b) Any Person acquiring an interest in a Book-Entry Certificate or a
Global Certificate which is a Subordinate Certificate, by acquisition of such
Certificate, shall be deemed to have represented to the Trustee that it is
either: (i) not acquiring an interest in such Certificate directly or indirectly
by, or on behalf of, an employee benefit plan or other retirement arrangement
which is subject to Title I of ERISA and/or Section 4975 of the Code, or (ii)
such Person provides a representation or certification to the Trustee to the
effect that the transfer and/or holding of an interest in such Certificate and
the servicing, management and/or operation of the Trust and its assets: (I) will
not result in any prohibited transaction which is not covered under an
individual or class prohibited transaction exemption, including, but not limited
to, PTE 84-14, PTE 91-38, PTE 90-1, PTE 95-60 or PTE 96-23 and (II) will not
give rise to any additional fiduciary duties on the part of the Master Servicer
or the Trustee.

          (c) Any attempted or purported transfer of any Certificate in
violation of the provisions of Subsections (a) or (b) above shall be void AB
INITIO and such Certificate shall be considered to have been held continuously
by the prior permitted Certificateholder. Any transferor of any Certificate in
violation of such provisions, shall indemnify and hold harmless the Trustee from
and against any and all liabilities, claims, costs or expenses incurred by the
Trustee as a result of such attempted or purported transfer.

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

                         Payments to Certificateholders

          Section 6.01. DISTRIBUTIONS ON THE CERTIFICATES. (a) On each
Distribution Date, following application of Available Funds pursuant to clauses
(i) and (ii) of Section 4.03(b), the Trustee will withdraw remaining Group 1
Available Funds and Group 2 Available Funds from the related sub-account of the
Certificate Account and distribute them, together with (i) on the Distribution
Date in November 2001, the Accrued Interest Reimbursement Amount withdrawn from
the Accrued Interest Account (to be applied pursuant to clause FIRST below) and
(ii) in the case of distributions of Group Available Funds to the Holders of the
Senior Certificates of a Senior Certificate Group, any amounts advanced by the
Certificate Insurer in respect of such Senior Certificate Group and on deposit
in the appropriate subaccount of the Certificate Account, in the following order
of priority among the Certificates:

     FIRST, to each of the Group 1 Senior Certificates and the Group 2 Senior
     Certificates, from the related Group Available Funds, Accrued Certificate
     Interest for such Senior Certificate Group for such Distribution Date and,
     on the Distribution Date in November 2001, the portion of the Accrued
     Interest Reimbursement Amount allocable to such Senior Certificate Group;

     SECOND, to each of the Group 1 Senior Certificates and the Group 2 Senior
     Certificates, from the related Group Available Funds, Accrued Certificate
     Interest for such Senior Certificate Group remaining unpaid from prior
     Distribution Dates;

     THIRD, to each of the Group 1 Senior Certificates and the Group 2 Senior
     Certificates, from the related Group Available Funds, the related Senior
     Optimal Principal Amount, in reduction of the Current Principal Amount of

     Senior Certificate Group has been reduced to zero;

     FOURTH, on each Distribution Date on which:

          (i) the Current Principal Amount of one Senior Certificate Group has
     been reduced to zero and

          (ii) if such Distribution Date occurs on or prior to the Cross-Over
     Date, the Subordination Trigger has not been met,

     from any remaining Group Available Funds allocable to principal for such
     Senior Certificate Group (and not including any amounts advanced by the
     Certificate Insurer), to the other Senior Certificate Group, in reduction
     of the Current Principal Amount thereof, if any, until such Current
     Principal Amount has been reduced to zero;

     FIFTH, if on any Distribution Date the aggregate Current Principal Amount
     of any Senior Certificate Group, following distributions pursuant to
     clauses FIRST through FOURTH, would be greater than the aggregate Scheduled
     Principal Balance of the Mortgage Loans in the related Mortgage Loan Group
     and the Subordinate Certificates are still outstanding:

          (i) 100% of all Available Funds otherwise allocable to the Subordinate
     Certificates in respect of principal will be distributed to reduce the
     Current Principal Amount of such Senior Certificate Group until such
     Current Principal Amount equals the aggregate Scheduled Principal Balance
     of the Mortgage Loans in the related Mortgage Loan Group; and

          (ii) Accrued Certificate Interest otherwise allocable to the
     Subordinate Certificates on such Distribution Date will be reduced, if
     necessary, and distributed to such Senior Certificate Group in an amount
     equal to Accrued Certificate Interest for such Senior Certificate Group for
     such Distribution Date, calculated on the excess of the Current Principal
     Amount of such Senior Certificate Group over the aggregate Scheduled
     Principal Balance of the Mortgage Loans in the related Mortgage Loan Group.
     Any reduction in Accrued Certificate Interest allocable to the Subordinate
     Certificates will be allocated to the Subordinate Certificates in inverse

     Date, the Subordination Trigger has not been met,

     from any remaining Group Available Funds allocable to principal for such
     Senior Certificate Group (and not including any amounts advanced by the
     Certificate Insurer), to the Certificate Insurer, to reimburse it for
     amounts set forth in clause SIXTH above made in respect of the other Senior
     Certificate Group, if any, that remain unpaid after application of funds
     pursuant to clause SIXTH;

     EIGHTH, from any remaining Group 1 and Group 2 Available Funds, any costs,

     amount equal to and in the following order:

               (1) the Accrued Certificate Interest on such Class for such
          Distribution Date,

               (2) any Accrued Certificate Interest on such Class remaining
          undistributed from previous Distribution Dates and

               (3) such Class's Allocable Share for such Distribution Date, in
          reduction of the Current Principal Amount thereof; and

     ELEVENTH, any remaining Group 1 Available Funds to the Class R-1
     Certificates, and any remaining Group 2 Available Funds to the Class R-2
     Certificates.

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

          (c) Net Interest Shortfalls will be allocated among the

that would have been allocated to each Certificate in the absence of any Net
Interest Shortfall.

          Section 6.02. [Reserved]

          Section 6.03. ALLOCATION OF LOSSES. (a) On or prior to each

          Amount thereof has been reduced to zero; and

               SEVENTH, to the Senior Certificates of each Senior Certificate
          Group, in respect of a Mortgage Loan in the related Mortgage Loan
          Group.

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

          (c) Any Realized Losses allocated to a Class of Certificates pursuant
to Subsection 6.03(b) shall be allocated among the Certificates of such Class in
proportion to their respective Current Principal Amounts. Any allocation of
Realized Losses pursuant to this Subsection 6.03(c) shall be accomplished by
reducing the Current Principal Amount of the related Certificates on the related
Distribution Date in accordance with Subsection 6.03(d).

          (d) Realized Losses allocated in accordance with this Section 6.03
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.

          (e) On each Distribution Date, the Trustee shall determine the
Subordinate Certificate Writedown Amount, if any. Any such Subordinate
Certificate Writedown Amount shall effect a corresponding reduction in the
Current Principal Amount of each class of Subordinate Certificates in the
reverse order of their numerical Class designations.

          (f) [Reserved]

          (g) Realized Losses on Mortgage Loans occurring on or prior to the
Cross-Over Date will not be allocated among any Senior Certificates. As a result
of the subordination of the Subordinate Certificates in right of distribution,
such Realized Losses will be borne first by the Subordinate Certificates in
inverse order of their numerical Class designations.

          Section 6.04. [Reserved]

          Section 6.05. PAYMENTS. (a) [Reserved].

          (b) On each Distribution Date, other than the final Distribution Date,
the Trustee shall distribute to each Certificateholder of record on the
immediately preceding Record Date such Certificateholder's PRO RATA share (based
on the aggregate Fractional Undivided Interest represented by such Holder's
Certificates) of all amounts required to be distributed on such Distribution
Date to its Class. The Trustee shall calculate such amounts based upon the
information provided the Master Servicer pursuant to Subsection 6.07(b).

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

          Section 6.06. STATEMENTS TO CERTIFICATEHOLDERS. (a) Concurrently with
each distribution to Certificateholders, the Trustee shall make available to

          The Trustee may make the foregoing monthly statement (and, at its
option, any additional files containing the same information in an alternative

year, the Trustee shall cause to be furnished upon request to each Person who at
any time during the calendar year was a Certificateholder, a statement
containing the information set forth in clauses (a)(ii) and (a)(v) of this
Section 6.06 aggregated for such calendar year or applicable portion thereof
during which such Person was a Certificateholder. Such obligation of the Trustee

          The Master Servicer shall supply to the Trustee in a timely manner the

          the Master Servicer and the Trustee shall agree.

          Section 6.08. MONTHLY ADVANCES. If the Monthly Payment (together with
any advances from any Sub-Servicers) 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 exceeds the amount deposited in the applicable subaccount of the
Certificate Account which will be used for a Certificate Account Advance with
respect to such Mortgage Loan, the Master Servicer will deposit in the
applicable subaccount of the Certificate Account not later than the Advancing
Date immediately preceding the related Distribution Date an amount equal to such
deficiency net of the related Master Servicing Fee for such Mortgage Loan except
to the extent the Master Servicer determines any such advance to be
nonrecoverable from Liquidation Proceeds, Insurance Proceeds or future payments
on the Mortgage Loan for which such Monthly Advance was made. Subject to the
foregoing, the Master Servicer shall continue to make such advances through the
date that the related Mortgaged Property has, in the judgment of the Master
Servicer, been completely liquidated. Any amount used as a Certificate Account
Advance shall be replaced by the Master Servicer by deposit in the applicable
subaccount of the Certificate Account on or before any future date on which and
to the extent that funds in the applicable subaccount of the Certificate Account

present an Officer's Certificate to the Trustee (i) stating that the Master
Servicer elects not to make a Monthly Advance in a stated amount and (ii)

the foregoing, the Master Servicer shall not be obligated to make any Monthly
Advances in respect of delinquent payments of principal on Simple Interest
Loans.

          Section 6.09. COMPENSATING INTEREST PAYMENTS. The Master Servicer
shall deposit into each subaccount of the Certificate Account not later than the
Advancing Date immediately preceding the related Distribution Date an amount
equal to the lesser of (i) the aggregate amounts determined pursuant to
subclauses (a) and (b) of the definition of Interest Shortfall for the related
Mortgage Loan Group for the related Distribution Date and (ii) the Master
Servicing Fee for such Distribution Date (such amount, the "Compensating
Interest Payment"). The Master Servicer shall not be entitled to any
reimbursement of any Compensating Interest Payment. Notwithstanding the
foregoing, the Master Servicer shall not be obligated to make any Compensating
Interest Payments in respect of delinquent payments of interest on Simple
Interest Loans.

          Section 6.10. REPORTS OF FORECLOSURES AND ABANDONMENT OF MORTGAGED
PROPERTY. Each year the Master Servicer shall report or cause to be reported to
the Internal Revenue Service foreclosures and abandonments of any Mortgaged
Property as required by Section 3.12(e).

against, any claim, loss, liability or expense incurred on their part, arising
out of any breach by the Master Servicer of its obligations under this
Agreement, including the costs and expenses (including reasonable legal fees and
expenses) of defending themselves; provided, that with respect to any such
claim, 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
knowledge thereof and provided further, that the failure to give any such notice
shall not affect the Master Servicer's obligation to indemnify the Indemnified
Persons hereunder except, and only to the extent that, the failure to provide
such notice materially impairs the Master Servicer's defense in respect of such
claim. The Master Servicer shall assume the defense of any claim for which an
Indemnified Person is entitled to indemnification pursuant to this Section 7.03,
and the Master Servicer shall pay all expenses in connection therewith,

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

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

          (c) The Master Servicer and any director, officer, employee or agent
of the Master Servicer shall be indemnified by the Trust and held harmless
thereby against any loss, liability or expense incurred in connection with any
legal proceedings relating to this Agreement or the Certificates (including
reasonable legal fees and disbursements of counsel), other than (i) any loss,
liability or expense related to its 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) and (ii) any loss, liability
or expense incurred by reason of such Person'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. Any such indemnification shall be
payable only in the manner, and subject to the limitations set forth in,
Sections 4.03(a) and 6.01(a).

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

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

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

successor to the Master Servicer and the 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; and (iii) the Master Servicer assigning and

          requiring the same to be remedied, shall have been given to the Master
          Servicer by the Trustee or to the Master Servicer and the Trustee by
          the Holders of Certificates evidencing Fractional Undivided Interests
          aggregating not less than 25% of the Trust Fund; or

               (iii) The occurrence of any of the following:

                    (A) Realized Losses since the Cut-Off Date exceed 1.75% of
               the Scheduled Principal Balance of the Mortgage Loans as of the
               Cut-Off Date;

                    (B) Realized Losses since the Cut-Off Date exceed $205,000
               and either (1) Realized Losses over any twelve-month period
               exceed 1.00% of the then-current Scheduled Principal Balance of
               the Mortgage Loans or (2) the three-month rolling average of the
               90-day delinquency rate for the Mortgage Loans exceeds 6%;

                    (C) the Master Servicer fails to maintain a net worth
               (determined in accordance with generally accepted accounting
               principles) of at least $50,000,000; or

                    (D) The Bear Stearns Companies Inc. no longer owns or
               maintains voting control over the Master Servicer and the new
               owner is not acceptable to the Certificate Insurer in its sole
               discretion; or

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

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

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

In each and every such case, so long as such Event of Default with respect to
the Master Servicer shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the principal of the Trust Fund or, on the occurrence of an
Event of Default set forth in clause (iii) above, the Certificate Insurer (so
long as the Senior Certificates are outstanding or any amounts are owed to the
Certificate Insurer, and the Certificate Insurer is not in default under the
Certificate Insurance Policy), by notice in writing to the Master Servicer (and
to the Trustee if given by such Certificateholders or the Certificate Insurer),
with a copy to the Rating Agency, may terminate all of the rights and
obligations (but not the liabilities) of the Master Servicer under this
Agreement and in and to the Mortgage Loans and/or the REO Property serviced by
the Master Servicer and the proceeds thereof. Upon the receipt by the Master
Servicer of the written notice, all authority and power of the Master Servicer
under this Agreement, whether with respect to the Certificates, the Mortgage
Loans, REO Property or under any other related agreements, including the
Sub-Servicing Agreements (but only to the extent that such other agreements
relate to the Mortgage Loans or REO Property) shall, subject to Section 8.02,
automatically and without further action pass to and be vested in the Trustee
pursuant to this Section 8.01; and, without limitation, the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the Master
Servicer as attorney-in-fact or otherwise, any and all documents and other
instruments and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's rights and
obligations hereunder, including, without limitation, the transfer to the
Trustee of (i) the property and amounts which are then or should be part of the
Trust or which thereafter become part of the Trust; (ii) originals or copies of
all documents of the Master Servicer reasonably requested by the Trustee to
enable it to assume the Master Servicer's duties thereunder; and (iii) the
rights and obligations of the Master Servicer under any Sub-Servicing Agreements
with respect to the Mortgage Loans. In addition to any other amounts which are
then, or, notwithstanding the termination of its activities under this
Agreement, may become payable to the Master Servicer under this Agreement, the
Master Servicer shall be entitled to receive, out of any amount received on
account of a Mortgage Loan or REO Property, that portion of such payments which
it would have received as reimbursement pursuant to Section 3.14 if notice of
termination had not been given. The termination of the rights and obligations of
the Master Servicer shall not affect any obligations incurred by the Master
Servicer prior to such termination. Notwithstanding the foregoing, so long as
the Senior Certificates are outstanding or any amounts are owed to the
Certificate Insurer, and the Certificate Insurer is not in default under the
Certificate Insurance Policy, the Certificate Insurer shall have the right,
within 90 days following termination of the Master Servicer and assumption of
the duties of the Master Servicer by the Trustee, to appoint a successor
servicer other than the Trustee.

          Section 8.02. TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. (a) Upon the
receipt by the Master Servicer of a notice of termination pursuant to Section
8.01 or an Opinion of Independent Counsel pursuant to Section 7.05 to the effect
that the Master Servicer is legally unable to act or to delegate its duties to a
Person which is legally able to act, the Trustee shall automatically become the
successor in all respects to the Master Servicer in its capacity under this
Agreement and the transactions set forth or provided for herein and shall
thereafter be subject to all the responsibilities, duties, liabilities and
limitations on liabilities relating thereto placed on the Master Servicer by the
terms and provisions hereof; PROVIDED, HOWEVER, that (i) it is understood and
agreed by the parties hereto that there will be a period of transition (not to
exceed 90 days) before the servicing transfer from the Master Servicer to the
Trustee shall be fully effected and (ii) the Trustee (a) shall be under no
obligation to purchase any Mortgage Loan pursuant to Section 10.01; and (b)
shall have no obligation whatsoever with respect to any liability incurred by
the Master Servicer (other than to make advances deemed recoverable and not
previously made) at or prior to the time of receipt by the Master Servicer of
such notice or by the Trustee of such Opinion of Independent Counsel. As
compensation therefor, the Trustee shall be entitled to all funds relating to
the Mortgage Loans which the Master Servicer would have been entitled to retain
if the Master Servicer had continued to act hereunder, except for those amounts
due the Master Servicer as reimbursement for advances previously made or
expenses previously incurred. Notwithstanding the above, if the Certificate
Insurer has not appointed a successor servicer within 90 days after assumption
of the Trustee of the duties of the Master Servicer, the Trustee may, if it
shall be unwilling so to act, or shall, if it is legally unable so to act,
appoint or petition a court of competent jurisdiction to appoint, any
established housing and home finance institution which is a Fannie Mae or
Freddie Mac-approved servicer, and with respect to a successor to the Master
Servicer only, having a net worth of not less than $10,000,000, as the successor
to the Master Servicer hereunder in the assumption of all or any part of the
responsibilities, duties or liabilities of the Master Servicer hereunder.
Pending appointment of a successor to the Master Servicer hereunder, the Trustee
shall act in such capacity as hereinabove provided. In connection with such
appointment and assumption, the Trustee may, with the consent of the Certificate
Insurer (so long as the Senior Certificates are outstanding or any amounts are
owed to the Certificate Insurer pursuant to the Certificate Insurance Policy,
and the Certificate Insurer is not in default thereunder), make such
arrangements for the compensation of such successor out of payments on the
Mortgage Loans as it and such successor shall agree; PROVIDED, HOWEVER, that no
such compensation shall be in excess of that permitted the Trustee under this
Subsection 8.02(a), and that such successor shall undertake and assume the
obligations of the Trustee to pay compensation to any third Person acting as an
agent or independent contractor in the performance of master servicing
responsibilities hereunder. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession. So long as the Senior Certificates are outstanding or any
amounts are owed to the Certificate Insurer, and the Certificate Insurer is not
in default under the Certificate Insurance Policy, the Certificate Insurer must
provide prior written approval of the appointment of any such successor
servicer. The costs and expenses of the Trustee in connection with the
termination of the Master Servicer, appointment of a successor servicer and
transfer of servicing, to the extent not paid by the terminated Master Servicer,
will be paid out of the Certificate Account, subject to the limitations and as
set forth in Sections 4.03(b) and 6.01(a).

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

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

          Section 8.04. WAIVER OF DEFAULTS. The Trustee shall transmit by mail
to all Certificateholders and the Certificate Insurer, 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 Master Servicer shall give notice of any such waiver to the Rating Agency.

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

                                   ARTICLE IX

                             Concerning the Trustee

          Section 9.01. DUTIES OF TRUSTEE. (a) The Trustee, prior to the
occurrence of an Event of Default and after the curing or waiver of all Events
of Default which may have occurred, undertakes to perform such duties and only
such duties as are specifically set forth in this Agreement as duties of the
Trustee. 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 use the same degree of care and skill in their exercise, as a
prudent person would exercise under the circumstances in the conduct of his own
affairs.

          (b) Upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments which are specifically
required to be furnished to the Trustee pursuant to any provision of this
Agreement, the Trustee shall examine them to determine whether they are in the
form required by this Agreement; PROVIDED, HOWEVER, that the Trustee shall not
be responsible for the accuracy or content of any resolution, certificate,
statement, opinion, report, document, order or other instrument furnished by the
Master Servicer hereunder, and PROVIDED FURTHER, that the Trustee shall have no
obligation to verify or recalculate any information provided therein.

          (c) The Trustee shall make monthly distributions and the final
distribution to the Certificateholders from funds in the Certificate Account as
provided in Sections 4A.01, 6.01 and 10.01 herein based on the applicable
monthly reports.

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

               (i) Prior to the occurrence of an Event of Default, and after the
          curing or waiver of all such Events of Default which may have
          occurred, the duties and obligations of the Trustee shall be
          determined solely by the express provisions of this Agreement, the
          Trustee shall not be liable except for the performance of such 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 and, in the absence of bad faith on the part of
          the Trustee, the Trustee may conclusively rely, as to the truth of the
          statements and the correctness of the opinions expressed therein, upon
          any certificates or opinions furnished to the Trustee and conforming
          to the requirements of this Agreement;

               (ii) The Trustee shall not be liable for an error of judgment
          made in good faith by a Responsible Officer or Responsible Officers of
          the Trustee, unless it shall be proved that the Trustee was negligent
          in ascertaining the pertinent facts;

               (iii) The Trustee shall not be liable with respect to any action
          taken, suffered or omitted to be taken by it in good faith in
          accordance with the directions of the Holders of Certificates
          evidencing Fractional Undivided Interests aggregating not less than
          51% of the Trust Fund (or if a higher percentage is specified herein
          for direction by the Holders, such higher percent) or, where
          applicable, of the Certificate Insurer given in accordance with this
          Agreement, 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 exercising any trust or other power conferred upon the
          Trustee, under this Agreement; and

               (iv) The Trustee shall not be required to take notice or be
          deemed to have notice or knowledge of any default or Event of Default
          unless a Responsible Officer of the Trustee's corporate trust
          department 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 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 has been advised of the
          likelihood of such loss or damage and regardless of the form of
          action; and

               (vii) None of the Master Servicer, the Seller, the Certificate
          Insurer or the Trustee shall be responsible for the acts or omissions
          of the others, it being understood that this Agreement shall not be
          construed to render them partners, joint venturers or agents of one
          another.

          The Trustee shall not 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 to perform, or be responsible for the manner of performance of, any
of the obligations of the Master Servicer under this Agreement, except during
such time, if any, as the Trustee shall be the successor to, and be vested with
the rights, duties, powers and privileges of, the Master Servicer in accordance
with the terms of this Agreement.

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

          (f) Except for those actions that the Trustee is required to take
hereunder and following an Event of Default and before its cure or waiver, the
Trustee shall have no obligation or liability to take any action or to refrain
from taking any action hereunder in the absence of written direction as provided
in this Agreement.

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

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

               (ii) The Trustee may consult with counsel and 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 Opinion of Counsel;

               (iii) The Trustee shall be under no obligation to exercise any of
          the trusts or powers vested in it by this Agreement, other than its
          obligation to give notices pursuant to this Agreement, or to
          institute, conduct or defend any litigation hereunder or in relation
          hereto at the request, order or direction of any of the
          Certificateholders pursuant to the provisions of this Agreement,
          unless such Certificateholders shall have offered to the Trustee
          reasonable security or indemnity against the costs, expenses and
          liabilities which may be incurred therein or thereby. Nothing
          contained herein shall, however, relieve the Trustee of the
          obligation, upon the occurrence of an Event of Default of which a
          Responsible Officer of the Trustee's corporate trust department has
          actual knowledge (which has not been cured) 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) The Trustee shall not be liable 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) 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, the Trustee shall not be bound to make any investigation
          into the facts or matters stated in any resolution, certificate,
          statement, instrument, opinion, report, notice, request, consent,
          order, approval, bond or other paper or document, unless requested in
          writing to do so by Holders of Certificates evidencing Fractional
          Undivided Interests aggregating not less than 25% of the Trust Fund
          and provided that the payment within a reasonable time to the Trustee
          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,
          reasonably assured to the Trustee by the security afforded to it by
          the terms of this Agreement. The Trustee 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 may execute any of the trusts or powers
          hereunder or perform any duties hereunder either directly or through
          agents or attorneys; PROVIDED, HOWEVER, that the Trustee may not
          appoint any agent to perform its custodial or paying agent functions
          under this Agreement without the express written consent of the Master
          Servicer, which consent will not be unreasonably withheld. The Trustee
          shall not be liable or responsible for the misconduct or negligence of
          any of the Trustee's agents or attorneys or a custodian or paying
          agent appointed hereunder if and only if such appointment was made by
          the Trustee with due care, with the prior written approval of the
          Certificate Insurer, and, when required, with the consent of the
          Master Servicer;

               (vii) Should the Trustee deem the nature of any action required
          on its part, other than a payment or transfer under Subsection 4.02(b)
          or Section 4.03, to be unclear, the Trustee may require prior to such
          action that it be provided by the Master Servicer with reasonable
          further instructions;

               (viii) The right of the Trustee to perform any discretionary act
          enumerated in this Agreement shall not be construed as a duty, and the
          Trustee shall not be accountable for other than its negligence or
          willful misconduct in the performance of any such act;

               (ix) The Trustee shall not be required to give any bond or surety
          with respect to the execution of the trust created hereby or the
          powers granted hereunder;

               (x) The Trustee shall have no duty to conduct any affirmative
          investigation as to the occurrence of any condition requiring the
          repurchase of any Mortgage Loan by the Seller pursuant to this
          Agreement or the eligibility of any Mortgage Loan for purposes of this
          Agreement; and

               (xi) To the extent the Trustee has not received a required
          remittance from the Master Servicer on or prior to a Distribution
          Date, it shall not be required to make the distribution provided for
          in Section 6.01 until it has received such funds.

          Section 9.03. TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.
The recitals contained herein and in the Certificates (other than the signature
and countersignature of the Trustee on the Certificates) shall be taken as the
statements of the Seller, and the Trustee shall have no responsibility for their
correctness. The Trustee makes no representation as to the validity or
sufficiency of the Certificates (other than the signature and countersignature
of the Trustee on the Certificates) or of any Mortgage Loan except as expressly
provided in Sections 2.02 and 2.05 hereof. 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. The Trustee shall not be
accountable for the use or application by the Seller of any of the Certificates
or of the proceeds of such Certificates, or for the use or application of any
funds paid to the Seller with respect to the Mortgage Loans. Subject to the
provisions of Section 2.05, the Trustee shall not be responsible for the
legality or validity of this Agreement or any document or instrument relating to
this Agreement, the validity of the execution of this Agreement or of any
supplement hereto or instrument of further assurance, or the validity, priority,
perfection or sufficiency of the security for the Certificates issued hereunder
or intended to be issued hereunder. The Trustee shall at no 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. The Trustee shall have no 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 9.04. TRUSTEE MAY OWN CERTIFICATES. The Trustee in its
individual capacity or in any capacity other than as Trustee hereunder may
become the owner or pledgee of any Certificates with the same rights it would
have if it were not Trustee, and may otherwise deal with the parties hereto.

          Section 9.05. TRUSTEE'S FEES AND EXPENSES. (a) The Trustee will be
entitled to net earnings on Permitted Investments of funds in the Certificate
Account. The Trust Fund will be liable for the Trustee's expenses, including all
reasonable out-of-pocket expenses, disbursements and advances incurred or made
by the Trustee 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 Master Servicer hereunder. Such expenses shall only be payable, on each
Distribution Date, as set forth in Sections 4.03(b) and 6.01(a). 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.

          (b) To the extent not otherwise indemnified against by the Master
Servicer hereunder, the Trust shall indemnify the Indemnified Persons for, and
will hold them harmless against, any loss, liability or expense incurred on
their part, arising out of, or in connection with, this Agreement and the
Certificates, including the costs and expenses (including reasonable legal fees
and expenses) of defending themselves against any such claim other than (i) any
loss, liability or expense related to such Indemnified Person's failure to
perform such Indemnified Person's duties in strict compliance with this
Agreement (except as any such loss, liability or expense shall be otherwise
reimbursable pursuant to this Agreement) and (ii) any loss, liability or expense
incurred by reason of such Indemnified Person's willful misfeasance, bad faith
or negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder. Such indemnification shall only
be payable, on each Distribution Date, as set forth in Sections 4.03(b) and
6.01(a). This indemnity shall survive the resignation or removal of the Trustee
and the termination of this Agreement. Section 9.06. ELIGIBILITY REQUIREMENTS
FOR TRUSTEE. The Trustee and any successor Trustee shall during the entire
duration of this Agreement be a state bank or trust company or a national
banking association organized and doing business under the laws of such state or
the United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus and undivided profits of at
least $40,000,000 or, in the case of a successor Trustee, $50,000,000, subject
to supervision or examination by federal or state authority and, in the case of
a successor Trustee other than pursuant to Section 9.10, rated in one of the
three highest long-term debt categories of, or otherwise acceptable to, each of
the Rating Agency. The Trustee shall not be an Affiliate of the Master Servicer,
unless the Trustee acts as successor Master Servicer hereunder. If the Trustee
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 9.06 the combined capital and surplus of such
corporation shall be deemed to be its total equity capital (combined capital and
surplus) as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 9.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 9.08.

          Section 9.07. INSURANCE. The Trustee, at its 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 which act as custodians for investor-owned mortgage pools. A
certificate of an officer of the Trustee as to the Trustee's compliance with
this Section 9.07 shall be furnished to the Master Servicer or any
Certificateholder upon reasonable written request.

          Section 9.08. RESIGNATION AND REMOVAL OF THE TRUSTEE. (a) The Trustee
may at any time resign and be discharged from the Trust hereby created by giving
written notice thereof to the Master Servicer and the Certificate Insurer, with
a copy to the Rating Agency. Upon receiving such notice of resignation, the
Master Servicer shall promptly appoint a successor Trustee by written
instrument, in triplicate, one copy of which instrument shall be delivered to
each of the resigning Trustee and the successor Trustee. If no successor Trustee
shall have been so appointed and have accepted appointment within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

          (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 9.06 and shall fail to resign after
written request therefor by the Master Servicer or if at any time the Trustee
shall become incapable of acting, or shall be adjudged a bankrupt or insolvent,
or a receiver of the Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, then the
Master Servicer shall be entitled to remove the Trustee and appoint a successor
Trustee by written instrument, in triplicate, one copy of which instrument shall
be delivered to each of the Trustee so removed and the successor Trustee.

          (c) The Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% of the Trust Fund may at any time remove
the Trustee and appoint a successor Trustee by written instrument or
instruments, in triplicate, signed by such Holders or their attorneys-in-fact
duly authorized, one complete set of which instruments shall be delivered to
each of the Master Servicer, the Trustee so removed and the successor so
appointed.

          (d) No resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 9.08 shall
become effective except upon appointment of and acceptance of such appointment
by the successor Trustee as provided in Section 9.09. So long as the Senior
Certificates are outstanding or any amounts are owed to the Certificate Insurer,
and the Certificate Insurer is not in default under the Certificate Insurance
Policy, the Certificate Insurer shall have the right to (i) remove the Trustee,
upon material breach by the Trustee of any obligation or covenant of the Trustee
pursuant to this Agreement (after the expiration of any applicable cure period)
and direct the appointment of a successor Trustee and (ii) upon resignation or
removal of the Trustee, approve the appointment of any successor Trustee.

          Section 9.09. SUCCESSOR TRUSTEE. (a) Any successor Trustee appointed
as provided in Section 9.08 shall execute, acknowledge and deliver to the Master
Servicer and to its predecessor Trustee an instrument accepting such appointment
hereunder. The resignation or removal of the predecessor Trustee shall then
become effective and such successor Trustee, without any further act, deed or
conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as Trustee herein. The predecessor Trustee shall after payment of its
outstanding fees and expenses promptly deliver to the successor Trustee all
assets and records of the Trust held by it hereunder, and the Master Servicer
and the predecessor Trustee shall execute and deliver such instruments and do
such other things as may reasonably be required for more fully and certainly
vesting and confirming in the successor Trustee all such rights, powers, duties
and obligations.

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

          (c) Upon acceptance of appointment by a successor Trustee as provided
in this Section 9.09, the successor Trustee shall mail notice of the succession
of such Trustee hereunder to all Certificateholders at their addresses as shown
in the Certificate Register and to the Rating Agency. The Master Servicer shall
pay the cost of any mailing by the successor Trustee.

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

          Section 9.11. APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE. (a)
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust or property constituting the same may at the time be located, the 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 and the Master Servicer to act as co-trustee or co-trustees, jointly
with the Trustee, or separate trustee or separate trustees, of all or any part
of the Trust, and to vest in such Person or Persons, in such capacity, such
title to the Trust, or any part thereof, and, subject to the other provisions of
this Section 9.11, such powers, duties, obligations, rights and trusts as the
Master Servicer and the Trustee may consider necessary or desirable. So long as
the Senior Certificates are outstanding or any amounts are owed to the
Certificate Insurer, and the Certificate Insurer is not in default under the
Certificate Insurance Policy, the Certificate Insurer shall have the right to
approve the appointment of any co-trustee or separate trustee.

          (b) If the Master Servicer shall not have joined in such appointment
within 15 days after the receipt by it of a written request so to do, or in case
an Event of Default with respect to the Master Servicer shall have occurred and
be continuing, the Trustee shall have the power to make such appointment without
the Master Servicer.

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

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

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

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

          (g) No trustee under this Agreement shall be personally liable by
reason of any act or omission of another trustee under this Agreement. The
Master Servicer and the Trustee acting jointly may at any time accept the
resignation of or remove any separate trustee or co-trustee, except that
following the occurrence of any Event of Default which has not been cured, the
Trustee acting alone may accept the resignation of or remove any separate
trustee or co-trustee.

          Section 9.12. MASTER SERVICER SHALL PROVIDE INFORMATION AS REASONABLY
REQUIRED. The Master Servicer shall furnish to the Trustee and the Certificate
Insurer, during the term of this Agreement, such periodic, special, or other
reports or information (and in such electronic format or other means acceptable
to the Trustee or the Certificate Insurer, as the case may be) as may reasonably
be requested by either the Trustee or the Certificate Insurer in order to
fulfill its duties and obligations under this Agreement.

          Section 9.13. FEDERAL INFORMATION RETURNS AND REPORTS TO
CERTIFICATEHOLDERS. (a) For Federal income tax purposes, the taxable year of
each of REMIC I and REMIC II shall be a calendar year and the Trustee shall
maintain or cause the maintenance of the books of each of REMIC I and REMIC II
on the accrual method of accounting.

          (b) The Trustee shall prepare and file or cause to be filed with the
Internal Revenue Service Federal tax information returns with respect to each of
REMIC I and REMIC II, the Trust Fund, if applicable, and the Certificates
containing such information and at the times and in the manner as may be
required by the Code or applicable Treasury regulations, and shall furnish to
each Holder of Certificates at any time during the calendar year for which such
returns or reports are made such statements or information at the times and in
the manner as may be required thereby. The Trustee 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. In
connection with the foregoing, the Trustee shall provide the name and address of
the person who can be contacted to obtain information required to be reported to
the holders of regular interests in each of REMIC I and REMIC II (the "REMIC
Reporting Agent") to the extent required by IRS Form 8811. The Trustee shall
make the elections to treat each of the REMIC I and REMIC II as a REMIC (which
election shall apply to the taxable period ending December 31, 2001 and each
calendar year thereafter) in such manner as the Code or applicable Treasury
regulations may prescribe. The Trustee shall sign all tax information returns
filed pursuant to this Section and any other returns as may be required by the
Code, and in doing so shall rely entirely upon, and shall have no liability for
information provided by, or calculations provided by, the Seller or the Master
Servicer. The Holder of each of the Class R-1 and Class R-2 Certificates is
hereby designated as the "Tax Matters Person" (within the meaning of Treas. Reg.
ss.ss. 1.860F-4(d)) for REMIC I and REMIC II, respectively. The Trustee is
hereby designated and appointed as the agent of each such Tax Matters Person.
Any Holder of a Residual Certificate will by acceptance thereof appoint the
Trustee as agent and attorney-in-fact for the purpose of acting as Tax Matters
Person for the related REMIC during such time as the Trustee does not own any
such Residual Certificate. In the event that the Code or applicable Treasury
regulations prohibit the Trustee from signing tax or information returns or
other statements, or the Trustee from acting as Tax Matters Person (as an agent
or otherwise), the Trustee shall take whatever action that in its sole good
faith judgment is necessary for the proper filing of such information returns or
for the provision of a tax matters person, including designation of the Holder
of a Residual Certificate to sign such returns or act as tax matters person.
Each Holder of a Residual Certificate shall be bound by this Section.

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

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

                                   Termination

          Section 10.01. TERMINATION UPON REPURCHASE BY THE SELLER OR ITS
DESIGNEE OR LIQUIDATION OF ALL MORTGAGE Loans. (a) Subject to Section 10.02, the
respective obligations and responsibilities of the Seller, the Master Servicer
and the Trustee created hereby, other than the obligation of the Trustee or the
Master Servicer to make payments to Certificateholders as hereinafter set forth
and to the Trustee, shall terminate upon:

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

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

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

          (c) [Reserved.]

          (d) The right of the Master Servicer or its designee to repurchase all
Mortgage Loans pursuant to Section 10.01(a)(i) above shall be exercisable only
if (i) the aggregate Scheduled Principal Balance of such Mortgage Loans at the
time of any such repurchase is less than 1% of the Cut-off Date Scheduled
Principal Balance or (ii) the Seller based upon an Opinion of Counsel delivered
to the Trustee, has determined that the REMIC status of either REMIC has been
lost or that a substantial risk exists that such REMIC status will be lost for
the then-current taxable year. At any time thereafter, the Seller may elect to
terminate the Trust at any time, and upon such election, the Master Servicer or
its designee shall repurchase all the Mortgage Loans.

          (e) [Reserved].

          (f) Provided that the Trustee has received timely notice, the Trustee
shall give notice of any termination to the Certificateholders, with a copy to
the Rating Agency, upon which the Certificateholders shall surrender their
Certificates to the Trustee for payment of the final distribution and
cancellation. To the extent reasonably practical, such notice shall be given by
letter, mailed not earlier than the 15th day and not later than the 25th day of
the month next preceding the month of such final distribution, and shall specify
(i) the Distribution Date upon which final payment of the Certificates will be
made upon presentation and surrender of the Certificates at the office of the
Trustee therein designated, (ii) the amount of any such final payment and (iii)
that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made only upon presentation and surrender of the
Certificates at the office of the Trustee therein specified.

          (g) If the option of the Master Servicer to repurchase or cause the
repurchase of all Mortgage Loans under Section 10.01(a)(i) above is exercised,
the Master Servicer and/or its designee, as the case may be, shall deliver to
the Trustee for deposit in the Certificate Account, by the Business Day prior to
the applicable Distribution Date, an amount equal to the amount specified in
Section 10.01(a)(i), provided that amounts set forth in Section 10.01(a)(i)(c)
shall be paid directly to the Certificate Insurer. Upon the presentation and
surrender of the Certificates, the Trustee shall distribute an amount equal to
(i) the amount otherwise distributable to the Certificateholders (other than the
holders of the Residual Certificates) on such Distribution Date but for such
repurchase, (ii) the Current Principal Amount and any accrued but unpaid
interest at the Pass-Through Rate to the Certificateholders of each Class, and
(iii) the remainder to the Residual Certificateholders. If the Available Funds
are not sufficient to pay all of the related Certificates in full, any such
deficiency will be allocated to the outstanding Class or Classes of Subordinate
Certificates having the highest numerical designation or, if after the
Cross-Over Date, to the Senior Certificates pro rata. Upon deposit of the
required repurchase price and following such final Distribution Date, the
Trustee shall promptly release to the Master Servicer and/or its designee, as
the case may be, the Mortgage Files for the remaining Mortgage Loans, and the
Accounts shall terminate, subject to the Trustee's obligation to hold any
amounts payable to Certificateholders in trust without interest pending final
distributions pursuant to Subsection 10.01(i).

          (h) In the event that this Agreement is terminated by reason of the
payment or liquidation of all Mortgage Loans or the disposition of all property
acquired with respect to all Mortgage Loans under Subsection 10.01(a)(ii) above,
the Master Servicer shall deliver to the Trustee for deposit in the Certificate
Account all distributable amounts remaining in its Protected Account and shall
cause any Sub-Servicers to deliver to the Trustee for deposit in the Certificate
Account all distributable amounts remaining in their Protected Accounts. Upon
the presentation and surrender of the Certificates, the Trustee shall distribute
to the Certificateholders, in accordance with their respective interests, all
distributable amounts remaining in the Certificate Account, provided, that prior
to receipt by any Holder of a Subordinate Certificate of any such amounts, all
amounts due to the Certificate Insurer and the Trustee shall first have been
paid in full. Upon deposit by any Sub-Servicers of such distributable amounts
and delivery to the Trustee of an Officer's Certificate from the Master Servicer
certifying that such deposit has been made, and following such final
Distribution Date, the Trustee shall promptly release to the Master Servicer the
Mortgage Files for the remaining Mortgage Loans, and the Accounts shall
terminate, subject to the Trustee's obligation to hold any amounts payable to
the Certificateholders in trust without interest pending final distributions
pursuant to Subsection 10.01(ii).

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

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

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

               (ii) at or after the time of adoption of such a plan of complete
          liquidation and at or prior to the final Distribution Date, the
          Trustee shall sell for cash all of the assets of the Trust to or at
          the direction of the Seller; and

               (iii) at the time of the making of the final payment on the
          Certificates, the Trustee shall distribute or credit from the
          Certificate Account to the extent on deposit therein (or cause to be
          distributed or credited) (i) to the Certificateholders, other than the
          Holders of the Residual Certificates, the Current Principal Amount of
          the Certificates plus 30 days' interest thereon at the applicable
          Pass-Through Rate, and (ii) to the Holder of the Class R-1
          Certificate, all remaining cash on hand from REMIC I and to the Holder
          of the Class R-2 Certificate, all remaining cash on hand from REMIC II
          (other than cash retained to meet claims); and the Trust and REMIC I
          and REMIC II shall terminate at such time provided that, prior to
          receipt by any Holder of a Subordinate Certificate of any such
          amounts, all amounts due to the Certificate Insurer and the Trustee
          shall first have been paid in full.

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

                            Miscellaneous Provisions

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

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

          (b) This Agreement may also be amended from time to time by the
Seller, the Trustee and the Master Servicer, with the consent of the Holders of
Certificates evidencing Fractional Undivided Interests aggregating not less than
51% of the Trust Fund or of the applicable Class or Classes if such amendment
affects only such Class or Classes, for the purpose of adding any provisions to

rights of the Certificateholders; PROVIDED, HOWEVER, that no such amendment
shall (i) reduce in any manner the amount of, or delay the timing of, payments
received on Mortgage Loans which are required to be distributed on any
Certificate without the consent of the Holder of such Certificate, (ii) reduce
the aforesaid percentage of Certificates the Holders of which are required to
consent to any such amendment, without the consent of the Holders of all

Certificate Insurer without the Certificate Insurer's consent or (iv) cause
either REMIC I or REMIC II to fail to qualify as a REMIC for federal income tax
purposes, as evidenced by an Opinion of Independent Counsel which shall be
provided to the Trustee other than at the Trustee's expense. Notwithstanding any
other provision of this Agreement, for purposes of the giving or withholding of
consents pursuant to this Section 11.02(b), Certificates registered in the name
of or held for the benefit of the Seller, the Master Servicer or a Sub-Servicer
or any Affiliate thereof shall be entitled to vote their Fractional Undivided
Interests with respect to matters affecting such Certificates.

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

          (d) In the case of an amendment under Subsection 11.02(b) above, it
shall not be necessary for any Certificateholder, other than the Certificate
Insurer exercising the rights of a Certificateholder pursuant to Section 11.06,
to approve the particular form of such an amendment. Rather, it shall be
sufficient if such Certificateholders approve the substance of the amendment.
The manner of obtaining such consents and of evidencing the authorization of the
execution thereof by such Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

          (e) 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, to the effect that such amendment will not (other than an amendment
pursuant to clause (ii) of, and in accordance with, Section 11.02(b)) 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 elections 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 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.

          Section 11.03. RECORDATION OF AGREEMENT. To the extent permitted by
applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the Mortgaged Properties are situated, and
in any other appropriate public recording office or elsewhere. The Master
Servicer shall effect such recordation, at its 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.

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

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

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

          (d) No one or more Certificateholders shall have any right by virtue
of any provision of this Agreement to affect the rights of any other
Certificateholders or to obtain or seek to obtain priority or preference over
any other such Certificateholder, or to enforce any right under this Agreement,
except in the manner herein provided and for the equal, ratable and common
benefit of all Certificateholders. For the protection and enforcement of the
provisions of this Section 11.04, each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

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

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

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

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

          (e) In determining whether the Holders of the requisite percentage of
Certificates evidencing Fractional Undivided Interests have given any request,
demand, authorization, direction, notice, consent or waiver hereunder,
Certificates owned by the Trustee, the Seller, the Master Servicer or any
Sub-Servicer or any Affiliate thereof shall be disregarded except as otherwise
provided in Section 11.02(b) and except that, in determining whether the Trustee
shall be protected in relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Certificates which the Trustee knows
to be so owned shall be so disregarded. Certificates which have been pledged in
good faith to the Trustee, the Seller, the Master Servicer or any Sub-Servicer
or any Affiliate thereof may be regarded as outstanding if the pledgor
establishes to the satisfaction of the Trustee the pledgor's right to act with
respect to such Certificates and that the pledgor is not an Affiliate of the
Trustee, the Seller, the Master Servicer or any Sub-Servicer, as the case may
be.

          Section 11.06. CONTROL BY CERTIFICATE INSURER. So long as the Senior
Certificates are outstanding or any amounts are owed to the Certificate Insurer,
and the Certificate Insurer is not in default under the Certificate Insurance
Policy, the Certificate Insurer shall, in all cases where the Holders of the
Senior Certificates have any right to consent to or direct any action, have the
right to act in place of such Holders, such consent or direction to represent an
amount equal to the Fractional Undivided Interests represented by the Senior
Certificates.

          Section 11.07. GOVERNING LAW. THIS AGREEMENT AND THE CERTIFICATES
SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REFERENCE TO ITS CONFLICT OF LAWS RULES AND THE OBLIGATIONS, RIGHTS AND REMEDIES
OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

          Section 11.08. NOTICES. All demands and notices hereunder shall be in

shall be conclusively presumed to have been duly given, whether or not the
Certificateholder receives such notice.

          Section 11.09. SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall be for any
reason whatsoever held invalid, then such covenants, agreements, provisions or
terms shall be deemed severed 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.

          Section 11.10. SUCCESSORS AND ASSIGNS. The provisions of this
Agreement shall be binding upon and inure to the benefit of the respective
successors and assigns of the parties hereto.

          Section 11.11. ARTICLE AND SECTION HEADINGS. The article and section
headings herein are for convenience of reference only, and shall not limit or
otherwise affect the meaning hereof.

          Section 11.12. COUNTERPARTS. This Agreement may be executed in two or
more counterparts each of which when so executed and delivered shall be an
original but all of which together shall constitute one and the same instrument.

          Section 11.13. NOTICE TO RATING AGENCY. The Trustee shall use its best
efforts to promptly provide notice to the Rating Agency with respect to each of
the following of which it has actual knowledge:

          1. Any material change or amendment to this Agreement;

Trustee and the Master Servicer, respectively, shall promptly furnish to the
Rating Agency copies of the following:

          1. Each report to Certificateholders described in Section 6.06; and

          2. Each annual independent public accountants' servicing report
received as described in Section 3.16.

          Section 11.14. THIRD PARTY BENEFICIARY. The parties hereto agree that,
so long as the Senior Certificates are outstanding or any amount is owed to the
Certificate Insurer, and the Certificate Insurer is not in default under the
Certificate Insurance Policy, the Certificate Insurer is an intended third party
beneficiary hereunder.

STRUCTURED ASSET MORTGAGE INVESTMENTS INC., EMC MORTGAGE CORPORATION OR THE
TRUSTEE REFERRED TO BELOW OR ANY OF THEIR RESPECTIVE AFFILIATES AND IS NOT
GUARANTEED OR INSURED BY ANY GOVERNMENTAL AGENCY OR INSTRUMENTALITY. THE HOLDER

</TABLE>

THIS CERTIFIES THAT
is the registered owner of the Fractional Undivided Interest evidenced hereby in
the beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust") consisting primarily of conventional, first
lien, fixed rate, fully amortizing or balloon payment, mortgage loans, secured
by one- to four-family residences located primarily in California and Texas
(collectively, the "Mortgage Loans"), which will be sold to the Trust by
Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were
sold by EMC Mortgage Corporation ("EMC") in its individual capacity and as an
affiliate of SAMI and Bear, Stearns & Co. Inc ("the Underwriter"). EMC 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 was created pursuant to the Pooling and Servicing Agreement dated as of
the Cut-off Date specified above (the "Agreement"), by and among SAMI, as
seller, EMC, as Master Servicer, and Wells Fargo Bank Minnesota, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

Interest on this Certificate will accrue during the month prior to the month in
which a Distribution Date (as hereinafter defined) occurs on the Current
Principal Amount hereof at a per annum rate equal to the weighted average of the
Net Rates of the Group 1 Mortgage Loans less the Premium Rate owed to the
Certificate Insurer. The Trustee will distribute on the 25th day of each month,
or, if such 25th day is not a Business Day, the immediately following Business
Day (each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last Business Day of the calendar month preceding
the month of such Distribution Date, an amount equal to the product of the
Fractional Undivided Interest evidenced by this Certificate and the amount
required to be distributed to Holders of Certificates of the same Class as this
Certificate. The Assumed Final Distribution Date is the Distribution Date
immediately following the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

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

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.

                MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 2001-4

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

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the Trust 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
Master Servicer and the rights of the Certificateholders under the Agreement
from time to time by the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% (or in certain cases, Holders of Certificates of affected
Classes evidencing such percentage of the Fractional Undivided Interests
thereof). Any such consent by the Holder of this Certificate shall be conclusive
and binding on such Holder and upon all future Holders of this Certificate and
of any Certificate issued upon the transfer hereof or in lieu hereof whether or
not notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates. In certain instances the
consent of the Certificate Insurer is also required.

     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 in the City of Columbia, State of Maryland,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee. In the case of classes of
Certificates not registered under the Securities Act of 1933, as amended,
additional documentation will be required to be provided to the Trustee prior to
the effectiveness of a transfer.

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

     No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The 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 neither the Master Servicers, the Trustee nor any
such agent shall be affected by notice to the contrary.

     The obligations created by the Agreement and the Trust created thereby
(other than the obligations to make payments to Certificateholders with respect
to the termination of the Agreement) shall terminate upon the earlier of (i) the
later of the (A) final payment or other liquidation (or Monthly Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other related assets 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 Scheduled Principal Balance of the
Mortgage Loans is less than 1% of the aggregate Cut-off Date Scheduled Principal
Balance of the Mortgage Loans. The exercise of such right will effect the early
retirement of the Certificates. The Trust also may be terminated on any
Distribution Date upon the determination, based upon an opinion of counsel, that
the REMIC status of the REMIC Assets has been lost or that a substantial risk
exists that such status will be lost for the then current year. In no event,
however, will the Trust created by the Agreement continue beyond the expiration
of 21 years after the death of certain persons identified in the Agreement.

THIS CERTIFIES THAT
is the registered owner of the Fractional Undivided Interest evidenced hereby in
the beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust") consisting primarily of conventional, first
lien, fixed rate, fully amortizing or balloon payment, mortgage loans, secured
by one- to four-family residences located primarily in California and Texas
(collectively, the "Mortgage Loans"), which will be sold to the Trust by
Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were
sold by EMC Mortgage Corporation ("EMC") in its individual capacity and as an
affiliate of SAMI and Bear, Stearns & Co. Inc ("the Underwriter"). EMC 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 was created pursuant to the Pooling and Servicing Agreement dated as of
the Cut-off Date specified above (the "Agreement"), by and among SAMI, as
seller, EMC, as Master Servicer, and Wells Fargo Bank Minnesota, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

     Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
Current Principal Amount hereof at a per annum rate equal to the weighted
average of the Net Rates of the Group 2 Mortgage Loans less the Premium Rate
owed to the Certificate Insurer. The Trustee will distribute on the 25th day of
each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (each, a "Distribution Date"), commencing on the First
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the calendar
month preceding the month of such Distribution Date, an amount equal to the
product of the Fractional Undivided Interest evidenced by this Certificate and
the amount required to be distributed to Holders of Certificates of the same
Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date immediately following the latest scheduled maturity date of
any Mortgage Loan and is not likely to be the date on which the Current
Principal Amount of this Class of Certificates will be reduced to zero.

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

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.

THIS CERTIFIES THAT
is the registered owner of the Fractional Undivided Interest evidenced hereby in
the beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust") consisting primarily of conventional, first
lien, fixed rate, fully amortizing or balloon payment, mortgage loans, secured
by one- to four-family residences located primarily in California and Texas
(collectively, the "Mortgage Loans"), which will be sold to the Trust by
Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were
sold by EMC Mortgage Corporation ("EMC") in its individual capacity and as an
affiliate of SAMI and Bear, Stearns & Co. Inc (the "Underwriter"). EMC 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 was created pursuant to the Pooling and Servicing Agreement dated as of
the Cut-off Date specified above (the "Agreement"), by and among SAMI, as
seller, EMC, as Master Servicer, and Well Fargo Bank Minnesota, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

     Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
Current Principal Amount hereof at a per annum rate equal to the weighted
average of the Net Rates of each Mortgage Loan Group weighted in proportion to
the results of subtracting from the aggregate principal balance of each Mortgage
Loan Group the current Principal Amount of the related class of Senior
Certificates. The Trustee will distribute on the 25th day of each month, or, if
such 25th day is not a Business Day, the immediately following Business Day
(each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last Business Day of the calendar month preceding
the month of such Distribution Date, an amount equal to the product of the
Fractional Undivided Interest evidenced by this Certificate and the amount
required to be distributed to Holders of Certificates of the same Class as this
Certificate. The Assumed Final Distribution Date is the Distribution Date
immediately following the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

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

                MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 2001-4

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

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the Trust 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
Master Servicer and the rights of the Certificateholders under the Agreement
from time to time by the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% (or in certain cases, Holders of Certificates of affected
Classes evidencing such percentage of the Fractional Undivided Interests
thereof). Any such consent by the Holder of this Certificate shall be conclusive
and binding on such Holder and upon all future Holders of this Certificate and
of any Certificate issued upon the transfer hereof or in lieu hereof whether or
not notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates. In certain instances the
consent of the Certificate Insurer is also required.

     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 in the City of Columbia, State of Maryland,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee. In the case of classes of
Certificates not registered under the Securities Act of 1933, as amended,
additional documentation will be required to be provided to the Trustee prior to
the effectiveness of a transfer.

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

     No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The 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 neither the Master Servicers, the Trustee nor any
such agent shall be affected by notice to the contrary.

     The obligations created by the Agreement and the Trust created thereby
(other than the obligations to make payments to Certificateholders with respect
to the termination of the Agreement) shall terminate upon the earlier of (i) the
later of the (A) final payment or other liquidation (or Monthly Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other related assets 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 Scheduled Principal Balance of the
Mortgage Loans is less than 1% of the aggregate Cut-off Date Scheduled Principal
Balance of the Mortgage Loans. The exercise of such right will effect the early
retirement of the Certificates. The Trust also may be terminated on any
Distribution Date upon the determination, based upon an opinion of counsel, that
the REMIC status of the REMIC Assets has been lost or that a substantial risk
exists that such status will be lost for the then current year. In no event,
however, will the Trust created by the Agreement continue beyond the expiration
of 21 years after the death of certain persons identified in the Agreement.

THIS CERTIFIES THAT
is the registered owner of the Fractional Undivided Interest evidenced hereby in
the beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust") consisting primarily of conventional, first
lien, fixed rate, fully amortizing or balloon payment, mortgage loans, secured
by one- to four-family residences located primarily in California and Texas
(collectively, the "Mortgage Loans"), which will be sold to the Trust by
Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were
sold by EMC Mortgage Corporation ("EMC") in its individual capacity and as an
affiliate of SAMI and Bear, Stearns & Co. Inc (the "Underwriter"). EMC 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 was created pursuant to the Pooling and Servicing Agreement dated as of
the Cut-off Date specified above (the "Agreement"), by and among SAMI, as
seller, EMC, as Master Servicer, and Well Fargo Bank Minnesota, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

     Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
Current Principal Amount hereof at a per annum rate equal to the weighted
average of the Net Rates of each Mortgage Loan Group weighted in proportion to
the results of subtracting from the aggregate principal balance of each Mortgage
Loan Group the current Principal Amount of the related class of Senior
Certificates. The Trustee will distribute on the 25th day of each month, or, if
such 25th day is not a Business Day, the immediately following Business Day
(each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last Business Day of the calendar month preceding
the month of such Distribution Date, an amount equal to the product of the
Fractional Undivided Interest evidenced by this Certificate and the amount
required to be distributed to Holders of Certificates of the same Class as this
Certificate. The Assumed Final Distribution Date is the Distribution Date
immediately following the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

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

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.

provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

     Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
Current Principal Amount hereof at a per annum rate equal to the weighted
average of the Net Rates of each Mortgage Loan Group weighted in proportion to
the results of subtracting from the aggregate principal balance of each Mortgage
Loan Group the current Principal Amount of the related class of Senior
Certificates. The Trustee will distribute on the 25th day of each month, or, if
such 25th day is not a Business Day, the immediately following Business Day
(each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last Business Day of the calendar month preceding
the month of such Distribution Date, an amount equal to the product of the
Fractional Undivided Interest evidenced by this Certificate and the amount
required to be distributed to Holders of Certificates of the same Class as this
Certificate. The Assumed Final Distribution Date is the Distribution Date
immediately following the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

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

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.

                MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 2001-4

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

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the Trust 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
Master Servicer and the rights of the Certificateholders under the Agreement
from time to time by the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% (or in certain cases, Holders of Certificates of affected
Classes evidencing such percentage of the Fractional Undivided Interests
thereof). Any such consent by the Holder of this Certificate shall be conclusive
and binding on such Holder and upon all future Holders of this Certificate and
of any Certificate issued upon the transfer hereof or in lieu hereof whether or
not notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates. In certain instances the
consent of the Certificate Insurer is also required.

     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 in the City of Columbia, State of Maryland,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee. In the case of classes of
Certificates not registered under the Securities Act of 1933, as amended,
additional documentation will be required to be provided to the Trustee prior to
the effectiveness of a transfer.

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

     No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The 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 neither the Master Servicers, the Trustee nor any
such agent shall be affected by notice to the contrary.

     The obligations created by the Agreement and the Trust created thereby
(other than the obligations to make payments to Certificateholders with respect
to the termination of the Agreement) shall terminate upon the earlier of (i) the
later of the (A) final payment or other liquidation (or Monthly Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other related assets 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 Scheduled Principal Balance of the
Mortgage Loans is less than 1% of the aggregate Cut-off Date Scheduled Principal
Balance of the Mortgage Loans. The exercise of such right will effect the early
retirement of the Certificates. The Trust also may be terminated on any
Distribution Date upon the determination, based upon an opinion of counsel, that
the REMIC status of the REMIC Assets has been lost or that a substantial risk
exists that such status will be lost for the then current year. In no event,
however, will the Trust created by the Agreement continue beyond the expiration
of 21 years after the death of certain persons identified in the Agreement.

THIS CERTIFIES THAT
is the registered owner of the Fractional Undivided Interest evidenced hereby in
the beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust") consisting primarily of conventional, first
lien, fixed rate, fully amortizing or balloon payment, mortgage loans, secured
by one- to four-family residences located primarily in California and Texas
(collectively, the "Mortgage Loans"), which will be sold to the Trust by
Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were
sold by EMC Mortgage Corporation ("EMC") in its individual capacity and as an
affiliate of SAMI and Bear, Stearns & Co. Inc. (the "Underwriter"). EMC 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 was created pursuant to the Pooling and Servicing Agreement dated as of
the Cut-off Date specified above (the "Agreement"), by and among SAMI, as
seller, EMC, as Master Servicer, and Wells Fargo Bank Minnesota, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

Interest on this Certificate will accrue during the month prior to the month in
which a Distribution Date (as hereinafter defined) occurs on the Current
Principal Amount hereof at a per annum rate equal to the weighted average of the
Net Rates of each Mortgage Loan Group weighted in proportion to the results of
subtracting from the aggregate principal balance of each Mortgage Loan Group the
current Principal Amount of the related class of Senior Certificates. The
Trustee will distribute on the 25th day of each month, or, if such 25th day is
not a Business Day, the immediately following Business Day (each, a
"Distribution Date"), commencing on the First Distribution Date specified above,
to the Person in whose name this Certificate is registered at the close of
business on the last Business Day of the calendar month preceding the month of
such Distribution Date, an amount equal to the product of the Fractional
Undivided Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Certificates of the same Class as this Certificate.
The Assumed Final Distribution Date is the Distribution Date immediately
following the latest scheduled maturity date of any Mortgage Loan and is not
likely to be the date on which the Current Principal Amount of this Class of
Certificates will be reduced to zero.

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

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

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

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the Trust 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
Master Servicer and the rights of the Certificateholders under the Agreement
from time to time by the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% (or in certain cases, Holders of Certificates of affected
Classes evidencing such percentage of the Fractional Undivided Interests
thereof). Any such consent by the Holder of this Certificate shall be conclusive
and binding on such Holder and upon all future Holders of this Certificate and
of any Certificate issued upon the transfer hereof or in lieu hereof whether or
not notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates. In certain instances the
consent of the Certificate Insurer is also required.

     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 in the City of Columbia, State of Maryland,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee. In the case of classes of
Certificates not registered under the Securities Act of 1933, as amended,
additional documentation will be required to be provided to the Trustee prior to
the effectiveness of a transfer.

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

     No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The 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 neither the Master Servicers, the Trustee nor any
such agent shall be affected by notice to the contrary.

     The obligations created by the Agreement and the Trust created thereby
(other than the obligations to make payments to Certificateholders with respect
to the termination of the Agreement) shall terminate upon the earlier of (i) the
later of the (A) final payment or other liquidation (or Monthly Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other related assets 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 Scheduled Principal Balance of the
Mortgage Loans is less than 1% of the aggregate Cut-off Date Scheduled Principal
Balance of the Mortgage Loans. The exercise of such right will effect the early
retirement of the Certificates. The Trust also may be terminated on any
Distribution Date upon the determination, based upon an opinion of counsel, that
the REMIC status of the REMIC Assets has been lost or that a substantial risk
exists that such status will be lost for the then current year. In no event,
however, will the Trust created by the Agreement continue beyond the expiration
of 21 years after the death of certain persons identified in the Agreement.

THIS CERTIFIES THAT
is the registered owner of the Fractional Undivided Interest evidenced hereby in
the beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust") consisting primarily of conventional, first
lien, fixed rate, fully amortizing or balloon payment, mortgage loans, secured
by one- to four-family residences located primarily in California and Texas
(collectively, the "Mortgage Loans"), which will be sold to the Trust by
Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were
sold by EMC Mortgage Corporation ("EMC") in its individual capacity and as an
affiliate of SAMI and Bear, Stearns & Co. Inc. (the "Underwriter"). EMC 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 was created pursuant to the Pooling and Servicing Agreement dated as of
the Cut-off Date specified above (the "Agreement"), by and among SAMI, as
seller, EMC, as Master Servicer, and Wells Fargo Bank Minnesota, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

     Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
Current Principal Amount hereof at a per annum rate equal to the weighted
average of the Net Rates of each Mortgage Loan Group weighted in proportion to
the results of subtracting from the aggregate principal balance of each Mortgage
Loan Group the current Principal Amount of the related class of Senior
Certificates. The Trustee will distribute on the 25th day of each month, or, if
such 25th day is not a Business Day, the immediately following Business Day
(each, a "Distribution Date"), commencing on the First Distribution Date
specified above, to the Person in whose name this Certificate is registered at
the close of business on the last Business Day of the calendar month preceding
the month of such Distribution Date, an amount equal to the product of the
Fractional Undivided Interest evidenced by this Certificate and the amount
required to be distributed to Holders of Certificates of the same Class as this
Certificate. The Assumed Final Distribution Date is the Distribution Date
immediately following the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

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

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.

                MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 2001-4

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

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the Trust 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
Master Servicer and the rights of the Certificateholders under the Agreement
from time to time by the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% (or in certain cases, Holders of Certificates of affected
Classes evidencing such percentage of the Fractional Undivided Interests
thereof). Any such consent by the Holder of this Certificate shall be conclusive
and binding on such Holder and upon all future Holders of this Certificate and
of any Certificate issued upon the transfer hereof or in lieu hereof whether or
not notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates. In certain instances the
consent of the Certificate Insurer is also required.

     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 in the City of Columbia, State of Maryland,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee. In the case of classes of
Certificates not registered under the Securities Act of 1933, as amended,
additional documentation will be required to be provided to the Trustee prior to
the effectiveness of a transfer.

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

     No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The 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 neither the Master Servicers, the Trustee nor any
such agent shall be affected by notice to the contrary.

     The obligations created by the Agreement and the Trust created thereby
(other than the obligations to make payments to Certificateholders with respect
to the termination of the Agreement) shall terminate upon the earlier of (i) the
later of the (A) final payment or other liquidation (or Monthly Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other related assets 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 Scheduled Principal Balance of the
Mortgage Loans is less than 1% of the aggregate Cut-off Date Scheduled Principal
Balance of the Mortgage Loans. The exercise of such right will effect the early
retirement of the Certificates. The Trust also may be terminated on any
Distribution Date upon the determination, based upon an opinion of counsel, that
the REMIC status of the REMIC Assets has been lost or that a substantial risk
exists that such status will be lost for the then current year. In no event,
however, will the Trust created by the Agreement continue beyond the expiration
of 21 years after the death of certain persons identified in the Agreement.

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

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the Trust 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,

     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
Master Servicer and the rights of the Certificateholders under the Agreement
from time to time by the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% (or in certain cases, Holders of Certificates of affected
Classes evidencing such percentage of the Fractional Undivided Interests
thereof). Any such consent by the Holder of this Certificate shall be conclusive

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. In certain instances the
consent of the Certificate Insurer is also required.

     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 in the City of Columbia, State of Maryland,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee. In the case of classes of
Certificates not registered under the Securities Act of 1933, as amended,
additional documentation will be required to be provided to the Trustee prior to
the effectiveness of a transfer.

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

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

disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the

Distribution Date upon the determination, based upon an opinion of counsel, that
the REMIC status of the REMIC Assets has been lost or that a substantial risk
exists that such status will be lost for the then current year. In no event,
however, will the Trust created by the Agreement continue beyond the expiration

THIS CERTIFIES THAT
is the registered owner of the Fractional Undivided Interest evidenced hereby in
the beneficial ownership interest of the Class set forth above in a trust (the
"Trust") consisting primarily of conventional, first lien, fixed rate, fully
amortizing or balloon payment, mortgage loans, secured by one- to four-family
residences located primarily in California and Texas (collectively, the
"Mortgage Loans"), which will be sold to the Trust by Structured Asset Mortgage
Investments Inc. ("SAMI"). The Mortgage Loans were sold by EMC Mortgage
Corporation ("EMC") in its individual capacity and as an affiliate of SAMI and
Bear, Stearns & Co. Inc. (the "Underwriter"). EMC 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 was created pursuant
to the Pooling and Servicing Agreement dated as of the Cut-off Date specified
above (the "Agreement"), by and among SAMI, as seller, EMC, as Master Servicer,
and Wells Fargo Bank Minnesota, 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.

     This Certificate has no principal balance and does not bear interest. The
Assumed Final Distribution Date is the Distribution Date immediately following
the latest scheduled maturity date of any Mortgage Loan and is not likely to be
the date on which the Current Principal Amount of this Class of Certificates
will be reduced to zero. Following payment in full of all other classes of
certificates except the Residual Certificates the Trustee will distribute to the
holder of this Certificate any amounts remaining in the related REMIC.

     The 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.

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

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

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the Trust 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
Master Servicer and the rights of the Certificateholders under the Agreement
from time to time by the Master Servicer and the Trustee with the consent of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% (or in certain cases, Holders of Certificates of affected
Classes evidencing such percentage of the Fractional Undivided Interests
thereof). Any such consent by the Holder of this Certificate shall be conclusive
and binding on such Holder and upon all future Holders of this Certificate and
of any Certificate issued upon the transfer hereof or in lieu hereof whether or
not notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates. In certain instances the
consent of the Certificate Insurer is also required.

     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 in the City of Columbia, State of Maryland,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee. In the case of classes of
Certificates not registered under the Securities Act of 1933, as amended,
additional documentation will be required to be provided to the Trustee prior to
the effectiveness of a transfer.

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

     No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The 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 neither the Master Servicers, the Trustee nor any
such agent shall be affected by notice to the contrary.

     The obligations created by the Agreement and the Trust created thereby
(other than the obligations to make payments to Certificateholders with respect
to the termination of the Agreement) shall terminate upon the earlier of (i) the
later of the (A) final payment or other liquidation (or Monthly Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other related assets 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 Scheduled Principal Balance of the
Mortgage Loans is less than 1% of the aggregate Cut-off Date Scheduled Principal
Balance of the Mortgage Loans. The exercise of such right will effect the early
retirement of the Certificates. The Trust also may be terminated on any
Distribution Date upon the determination, based upon an opinion of counsel, that
the REMIC status of the REMIC Assets has been lost or that a substantial risk
exists that such status will be lost for the then current year. In no event,
however, will the Trust created by the Agreement continue beyond the expiration
of 21 years after the death of certain persons identified in the Agreement.

(other than the obligations to make payments to Certificateholders with respect
to the termination of the Agreement) shall terminate upon the earlier of (i) the
later of the (A) final payment or other liquidation (or Monthly Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other related assets 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 Scheduled Principal Balance of the
Mortgage Loans is less than 1% of the aggregate Cut-off Date Scheduled Principal
Balance of the Mortgage Loans. The exercise of such right will effect the early
retirement of the Certificates. The Trust also may be terminated on any
Distribution Date upon the determination, based upon an opinion of counsel, that
the REMIC status of the REMIC Assets has been lost or that a substantial risk
exists that such status will be lost for the then current year. In no event,
however, will the Trust created by the Agreement continue beyond the expiration
of 21 years after the death of certain persons identified in the Agreement.

or by leasehold for a term longer than the term of the related Mortgage, subject
only to (i) the lien of current real property taxes and assessments, (ii)

rights generally and by general equity principles (regardless of whether such
enforcement is considered in a proceeding in equity or at law); and, to the best

legal capacity to execute the Mortgage Note and the Mortgage and each Mortgage

to prevent the Mortgagor from being deemed to be a co-insurer thereunder; if the
improvement on the Mortgaged Property is a condominium unit, it is included
under the coverage afforded by a blanket policy for the condominium project; if
upon origination of the related Mortgage Loan, the improvements, if any, on the
Mortgaged Property were in an area identified as a federally designated flood

recorded as of the Closing Date;

leasehold payments or ground rents which may be due and owing against any
Mortgaged Property and all such charges have been paid when due;

guaranty, as applicable, shall remain in full force and effect after the sale of
the Mortgage Loans to the Trust, and such Mortgage Loans are not subject to any

applicable, and all prior transfers, if any, of such Mortgage Loans have been,

federal acts and regulations, and no circumstances exist with respect to such
Mortgage Loans which would permit the FHA or VA, as applicable, to deny coverage

               Class R-2 Certificates (THE "PRIVATELY OFFERED CERTIFICATES")

Dear Ladies and Gentlemen:

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

          (i)    we understand that the Privately Offered Certificates are not
                 being registered under the Securities Act of 1933, as amended
                 (the "Act") or any applicable state securities or "Blue Sky"
                 laws, and are being sold to us in a transaction that is exempt
                 from the registration requirements of such laws;

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

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

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

          (v)    we agree the Privately Offered Certificates must be held
                 indefinitely by us (and may not be sold, pledged, hypothecated
                 or in any way disposed of) unless subsequently registered under
                 the Act and any applicable state securities or "Blue Sky" laws
                 or an exemption from the registration requirements of the Act
                 and any applicable state securities or "Blue Sky" laws is
                 available;

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

                      (A) (1) the sale is to an Eligible Purchaser (as defined
                 below), (2) if required by the Pooling and Servicing Agreement
                 (as defined below) a letter to substantially the same effect as
                 either this letter or, if the Eligible Purchaser is a Qualified
                 Institutional Buyer as defined under Rule 144A of the Act, the
                 Rule 144A and Related Matters Certificate in the form attached
                 to the Pooling and Servicing Agreement (as defined below) (or
                 such other documentation as may be acceptable to the Trustee)

Ladies and Gentlemen:

     In accordance with Section 2.02 of the above-captioned Pooling and
Servicing Agreement, the undersigned, as Trustee, hereby certifies that, except
as otherwise noted on the attached exception report, that as to each Mortgage
Loan listed on the Mortgage Loan Schedule (other than any Mortgage Loan paid in
full or listed on the attachment hereto) it has reviewed the Mortgage File and
has determined that (i) each document required to be recorded has been returned
from the recording office with evidence of recording thereon and it has received
either an original or a copy of such document, as required pursuant to Section
2.01(b), PROVIDED, HOWEVER, that with respect to those documents described in
subclauses (b)(iv) and (b)(viii) of Section 2.01, it has reviewed only those
documents actually delivered to us pursuant to such subclauses; (ii) an original
title insurance policy (or if a master title policy has been issued by the title
insurer, a mortgagee's certificate of title insurance), if available, or a copy
thereof, whenever a title insurance binder or commitment or other assurance of
title was originally delivered; and (iii) the documents described in clauses (i)
and (ii) are related, determined on the basis of the Mortgagor name, original
principal balance and loan number, to the Mortgage Loans identified on the
Mortgage Loan Schedule and appear regular on their face.

     The Trustee has made no independent examination of any documents contained
in each Mortgage File beyond the review specifically required in the
above-referenced Pooling and Servicing Agreement. The Trustee makes no
representation that any documents specified in subclauses (iv) and (viii) of
Section 2.01(b) should be included in any Mortgage File. The Trustee makes no
representations as to: (i) the validity, legality, enforceability or genuineness
of any of the documents contained in each Mortgage File of any of the Mortgage
Loans identified on the Mortgage Loan Schedule or (ii) the collectability,
insurability, effectiveness or suitability of any such Mortgage Loan.
